PING Ultrasonic Distance Sensor and Arduino (Lesson #8)

[@SeanPatrickGo]

Hey, just wanted to say thank you for making these videos! I just started learning Ardunio by following you series and I've learned a lot already! Going to start watching your servo video tomorrow :)

I want to make a disc shooter that can be attached to the arm, and I want to add a control system to it, basically when the palm "blocks" the shot, the disc shooter will not fire. So I thought to connect this sensor to perform this operation, do you think it is correct? Does it suit my needs?

[@Science.Buddies]

This sensor should work to detect a human hand in front of it!

[@dannydemonicmusic]

Made for beginners! I love it!

[@Science.Buddies]

Thanks! Check out our other Arduino tutorials if you haven't already, they are also made for beginners.

Playing cereal killa while watching this makes it e en better

Very good video ! I've learnt a lot

[@entomafritzianb.5945]

Very Educational. Is it possible to detect passing objects using ultrasonic sensors?

[@Science.Buddies]

Yes, you can detect objects passing in front of the sensor since you will see a brief drop in the measured distance, then once the object has passed, the distance will go back up.

Great experiments

[@Bro_Bubby]

Please, explain the declaration of variable, "long duration, inches and cm;". What I don't actually understand is the "long". What is it and what is it used for?

[@Science.Buddies]

Hi - we don't have our own video on this, but there are different variable types for the Arduino that take up different amounts of memory and have different ranges. You can read more about them here: learn.sparkfun.com/tutorials/data-types-in-arduino/all

[@dontwannaatellu]

my sensor says vsc trig echo and ground?

[@Science.Buddies]

You probably have an HC-SR04, a similar sensor with four pins: kzbin.info/www/bejne/pF7Ke2NmfLmmhMksi=T3p15vhrKWOg7Qml

[@yuriivoina1261]

Hi :) could you be so kind to add the code for this tutorial ? thank you in advance

[@Science.Buddies]

The formatting gets messed up when we try to paste code into KZbin descriptions, but this is example code that comes built-in to the Arduino IDE!

[@Bro_Bubby]

I dont really get the concept of this code

[@JGambrosia]

340 m/s is not the same as 29 μ*s/cm. That’s like saying 1 m/s = 1 s/m Also to add insult to injury, 340 m/s is not the speed of sound. It’s 343 m/s.

bro mine has 4 legs

[@Studs_Studio]

the next video in the series is for that. i think im a little late for the response XD

wtf the ping is so expensive...
