Arduino Proximity Shield acts as Arduino Shield via 1Sheeld
This is a simple guide on how to make a distance detector using an Arduino, a HC-SRO4 Ultrasonic Sensor, a Buzzer, and some LED's.
Arduino library for distance sensors.
The module is very easy use , now with the library , user just need a function then he can get the distance .
The method uses two proximity sensor Relay Module for arduino (The number Determine the threshold at which the arduino must switch on the light .
