The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

The 38-KHz IRTR module is a compact design of an infrared transmitter and receiver board created with the help of a couple of inexpensive components. This builds off of the IR Decoder that we explored ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...
