Good night,
Going on with my adventures with Arduino and sensors, today I decided to play with Ultrasonic sensor HC-SR04 to measure distance.
HC-SR04 is pretty easy to work with, it has 4 pins, VCC to energy, Trig to start a measurement, Echo to get the distance, and GND to ground.
It has a library to get it working, it is called Ultrasonic. The only problem that I had was the Library is out of date, it still uses WProgram.h but Arduino 1.0.1 uses Arduino.h, so I updated it. (You can get on the end of the post).
The library must be included on your dir “arduino-1.0.1/libraries” and you must restart your IDE.
Sensor VCC connects to Arduino +5V pin
Sensor Trig connects to Arduino PIN 12
Sensor Echo connects to Arduino PIN 13
Sensor GND connnects to Arduino GND PIN
You can configure it on trig and echo variables.
[code lang=”c”]
#include “Ultrasonic.h”
int trig = 12;
int echo = 13;
Ultrasonic ultrasonic(trig,echo);
void setup() {
Serial.begin(9600);
}
void loop()
{
Serial.print(“Distance CM:”);
Serial.println(ultrasonic.Ranging(CM));
Serial.print(“Distance INC:”);
Serial.println(ultrasonic.Ranging(INC));
delay(100);
}
[/code]

Well crafted post, the structure flows naturally from one point to the next without forcing transitions, and a stop at motionwithclarity kept the same flow going, you can tell when a writer has thought about how their content reads rather than just what it contains and this is one of those examples.
Felt a small spark of recognition when the post named something I had been struggling to articulate, and a look at expertvertex produced more such moments, the rare service of giving readers language for fuzzy intuitions is one of the higher values that good writing can provide and this site offered several today instances.
Worth recognising the specific care that went into how this post ended, and a look at broadcastnova maintained the same careful conclusions, endings are where most blog content falls apart and this site has clearly invested in the closing stretches of its pieces rather than letting them simply trail off when energy fades.
Beats most of the alternatives on the topic by a noticeable margin, and a look at ideasrequiremovement did not change that at all, this is one of the better corners of the open internet for this kind of content and I am glad I clicked through rather than skipping past quickly like I usually do.
Reading this as part of my evening winding down routine fit perfectly, and a stop at momentumdesignlab extended the wind down nicely, content that calms rather than agitates is what I want at the end of the day and this site provides that calming reading experience reliably which is increasingly rare across the modern web.
Quality you can feel from the first paragraph, the writer clearly knows the topic and how to share it, and a quick look at progressrequiresfocus confirmed the same depth runs throughout the rest of the site as well which is rare and worth pointing out when it happens online for any reader passing through.
Closed several other tabs to focus on this one as I read, and a stop at directionbuildsvelocity held my undivided attention the same way, content that earns full focus in an attention environment full of competing pulls is content doing something genuinely well and the team behind it deserves recognition for that achievement consistently.
Now I want to find more sites like this but I suspect they are rare, and a look at actiondrivenshift extended that thought, the few sites that meet this quality bar are precious specifically because they are rare and finding others like them is one of the ongoing projects of careful internet curation across the years.
Found a small mental shift after reading this, the framing here is just a bit different from the standard takes online, and a look at growthpathwaynow extended that fresh perspective across more material, the rare site whose voice actually changes how you think about something rather than just confirming existing beliefs.
Did not expect much when I clicked through but ended up reading the whole thing carefully, and a stop at actiondrivenoutcomes kept that engagement going, sometimes the unassuming sites turn out to deliver more than the flashy ones which is something I have learned to look out for over time online lately and across topics.
Now planning to write about the topic myself eventually using this post as a reference, and a look at builddirectionnow would also serve in that future piece, content that becomes raw material for my own writing rather than just informing my reading is content with multiplicative value and this site is generating that multiplicative effect.
Bookmark folder created specifically for this site, and a look at visiontoexecution confirmed the dedicated folder was the right call, dedicated folders for individual sites are a level of organisation I rarely deploy and this site has earned that level of dedicated tracking based on the consistency I have seen so far across sessions.

A well calibrated piece that knew its scope and stayed inside it, and a look at pathwaytoaction maintained the same scope discipline, scope creep is one of the failure modes of long blog posts and this site has clearly invested in the editorial discipline to prevent it which shows up in tightly contained pieces.
Now feeling the quiet pleasure of finding writing that takes itself seriously without being self serious, and a stop at executeplansnow extended that subtle pleasure, the gap between earnest and pretentious is fine and this site has clearly chosen to land on the earnest side without slipping over into pretentious which is impressive.

Genuine pleasure to read, and that is not something I say often after a casual click through, and a quick visit to directionenablesmomentum kept the same feeling going across the rest of the site, finding writing that actually feels good to spend time with rather than just functional is increasingly rare on the open web.
Will be back, that is the simplest way to say it, and a quick visit to progresswithintent reinforced the decision, this site has earned a spot in my regular rotation alongside a few other reliable places I check when I want something genuinely informative without all the usual modern web noise getting in the way.
Worth pointing out the careful word choice in this post, no buzzwords and no jargon, and a look at ideasintoflow continued that disciplined vocabulary, sites that resist the pull of trendy language are sites that will read well in five years and this one is clearly built for that kind of long durability.
Felt like the writer was speaking directly to someone with my level of curiosity, neither talking down nor showing off, and a stop at progressstarter kept that comfortable matching going, finding writing that meets you where you are rather than asking you to climb up or stoop down feels great every time it happens.
Now recognising the specific pleasure of reading writing that shows real care for sentence shapes, and a look at actioncreatesflowstate extended that craft pleasure, sentence level writing quality is something most blog content ignores entirely and this site has clearly invested in the prose layer alongside the substance which is rare today.
After several visits I am now confident this site is one to follow seriously, and a stop at thinklessmovebetter reinforced that confidence, the gradual building of trust through repeated quality exposures is the only sustainable way to develop reader loyalty and this site is building that loyalty in me through patient consistent work consistently.
A piece that brought a sense of order to a topic I had been finding chaotic, and a look at visionguidesmotion continued that organising effect, content that imposes useful structure on messy subjects is doing genuine intellectual work and this site is providing that organisational function across multiple posts I have read recently here.
Felt like the post had been edited rather than just drafted and published, and a stop at directionpowersresults suggested the same care across the site, the difference between edited and unedited content is enormous for the reader and this site has clearly invested in the editing pass that most blogs skip entirely which really does show up.

Started reading skeptically because the headline seemed overconfident, and the post earned the headline by the end, and a look at progressoveractivity continued that pattern of earning its claims, sites that can back up their headlines without overpromising are rare and this one has clearly developed editorial calibration on that front consistently.
My time on this site has now extended past what I had budgeted, and a stop at clarityactivatesmotion keeps extending it further, content that overstays its budget in my schedule is content that has earned the extra time and this site has been earning extra time across multiple visits to the point where my schedule needs adjustment.
Now adjusting my expectations upward for the topic based on this post, and a stop at actionpathway continued that bar raising effect, content that resets what I think is possible on a subject is doing real work in shaping my standards and this site is providing those bar raising experiences at a notable rate during sessions.
Worth saying that the post fit naturally into a rhythm of careful reading, and a stop at directionstartsclarity extended the same rhythm, content that pairs well with how I actually read rather than demanding a different mode is content well calibrated to its likely audience and this site has clearly thought about that consistently.
Reading this brought back an idea I had set aside months ago, and a stop at progresswithpurpose added more substance to that idea, content that revives dormant projects in my own thinking is content with serious creative value and this site is contributing to my own work in ways I had not expected when first clicking through.
A particular pleasure to read this with a fresh coffee, and a look at happyfamilia extended the pleasure across more pages, content that pairs well with quiet morning rituals is something I have come to value highly and this site has the kind of energy that fits naturally into a calm reading routine.
Felt the post was written for someone like me without explicitly addressing me, and a look at thinklessmovebetter produced the same fit, when content lands on its target without pandering you know the writer has done careful audience thinking rather than relying on demographic targeting or interest signals to do the work of editorial decisions.
Got pulled in by the headline and stayed because the content actually delivered on the promise, and a stop at focusacceleration kept that trust intact, when a site lives up to its own framing it earns the right to keep showing up in my browser tabs going forward indefinitely from here on out really.
Felt the post had been written without using a single buzzword, and a look at directionsharpensfocus continued that clean vocabulary, content free of jargon and trendy phrases reads better and ages better and this site has clearly committed to a vocabulary that will not feel dated in three years which is impressive editorially.
Really appreciate the confidence to make a clear point rather than hedging everything, and a quick visit to growthinmotion maintained the same direct stance, writing that takes positions rather than equivocating is more useful even when the positions are debatable because at least the reader has something to react to clearly.
A clear case of writing that does not try to do too much in one post, and a look at progresswithdirectionalforce maintained the same scoped discipline, posts that try to cover too much end up covering nothing well and this site has clearly chosen scope discipline as a core editorial principle which shows up clearly in what I read.
A piece that did not lecture even when it had clear positions, and a look at directionsetsspeed maintained the same teaching without preaching tone, finding the line between informing and lecturing is hard and most sites land on the wrong side of it but this one has clearly figured out how to inform without becoming preachy.
Reading this triggered a small but real correction in something I had assumed, and a stop at directionisleverage extended that corrective effect, content that updates my beliefs through evidence rather than rhetoric is content with intellectual integrity and this site has earned that label consistently across the pieces I have read so far today.
Highly recommend to anyone looking for a sensible take on this topic without the usual marketing nonsense, and a look at growthfollowsfocus kept that grounded approach going, sites that stay focused on serving readers rather than monetising every click are rare and this is clearly one of those rare ones I really appreciate finding.
Reading this fit naturally into my afternoon walk because I was reading on my phone, and a stop at motionwithclarity continued well in that walking format, content that survives mobile reading without becoming awkward is content with format flexibility and this site has clearly thought about how it reads across different devices today.
Thanks for the practical examples scattered through the post rather than abstract theory only, and a look at forwardenergyactivated continued that grounded style, abstract points are easier to remember when paired with concrete situations and the writers here clearly understand how readers actually retain information from blog content reading sessions.
Adding to the bookmarks now before I forget, that is how good this is, and a look at actionwithstructure confirmed the rest of the site is worth saving too, this is one of those rare finds that justifies the time spent searching the web for once which is a relief in the current environment.
Quietly impressive in a way that does not announce itself, and a stop at ideasneedalignment extended that quiet impressiveness, the kind of quality that emerges through sustained attention rather than first impressions is the kind I trust more deeply and this site has been earning that deeper trust across multiple sessions over time consistently.
Solid value for anyone willing to read carefully, and a look at strategycreatesflow extends that value across the rest of the site, this is the kind of place that rewards return visits rather than offering everything in a single splashy post and then leaving readers nothing to come back for later which is unfortunately common.
A well calibrated piece that knew its scope and stayed inside it, and a look at growthmovesintentionally maintained the same scope discipline, scope creep is one of the failure modes of long blog posts and this site has clearly invested in the editorial discipline to prevent it which shows up in tightly contained pieces.
Just wanted to drop a quick note saying this was a useful read on a topic I have been circling, no fluff, and a stop at buildmotiondaily added a few extra points that fit the same simple style which makes the whole site feel coherent rather than thrown together by many different writers with different goals.
However selective I am about new bookmarks this one made it past my filter, and a look at directionunlocked confirmed the bookmark was worth the slot, the precious slots in my permanent bookmark folder are difficult to earn and this site earned one without making me think twice about whether the slot was justified by the quality.
