In this tutorial we discussed the Sound sensor, its pinout, working, and how to interface it with Arduino. This article includes a complete Arduino code and circuit diagram along with a step-by-step ...

In this Arduino IR sensor module tutorial we are explaining how to connect IR sensor module with Arduino Uno and write the code to get the IR motion sensor working.

Connect the A0 pin of the Arduino to the same column where the LDR and resistor is connected (Since the LDR gives out an analog voltage, it is connected to the analog input pin on the Arduino. The ...
