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 PCB should made with 2-oz copper to reduce unnecessary power loss in the circuit board. Photograph of a readymade ACS712 current sensor module is included here as an example. current sensor module ...

This module is similar to a scaled-up IR reflective object sensor; it combines an IR emitter and receiver on one end, and is pointed at a reflector placed across the track, up to 10 meters away.
