How to set up the Hc-SRO4 Ultrasonic Range Sensor
I got 2 of these a week ago there great but there not much on how to set them up so I figured I share how I did it.
First off you have to wire it up which from what I have read people was doing it wrong more then once. So here is how I got it to work .
I added the serial file so you can use the Serial Monitor to get reading in cm. The zip file has all you need to get this work.
Pin 9 is used for trig pin 10 is used for echo. Vcc to 5 volt pin on the arduino. And gnd to gnd on the arduino.
Here a picture to make it easy Great little range finder at great price
