How an Ultrasonic Sensor Works - Snippet from our Obstacle Avoidance Robot Tutorial

An incredibly brief overview of how an ultrasonic works, pulled from a quick review of the concept as we built a robot designed to mindlessly go around avoiding obstacles. Check out the full video here: • Ultrasonic sensor with...

Just wanted to let you know that you have been a big part of my introduction to electrical engineering. Keep doing what you’re doing!!

[@aakash59596]

Sir please make more electronics shorts❤❤

[@CircuitBread]

Just posted one today and have quite a few coming 😎

[@omniyambot9876]

I thought you will explain the analog circuitry lol

[@patrpatl]

If I am coding the formula I would not divide it into two, multiplies it to 170 instead.

[@wokeclub1844]

Is it guaranteed that speed of sound while sending is the same as its speed when reflected back? Would it not be a bit slower while coming back?

[@CircuitBread]

Hmmm... why would it be slower on the way back? Speed of sound is affected by environmental factors but it doesn't slow down over time. It will be weaker as the signal dissipates but just as fast.

[@wipoute]

​@@CircuitBread I think they might have meant: is the Doppler effect something to take into consideration? Is the relative speed of sound to the object it bounces of 340m/s ? or the absolute speed of sound to the environment 340m/s ?
