HC-SR04 ULTRASONIC RANGE SENSOR

Simple setup that works with the HC-SR04 ULTRASONIC RANGE SENSOR

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

The files you need to add to the arduino ide are here
