To build this project we will use an Arduino UNO with a pair of IR sensors and a motor driver. The IR sensors will be placed in front of the robot on each side. The IR sensor contains an IR LED and an ...

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 ...

LEDs on the Arduino can be programmed to indicate if the sensor is/isn’t immersed by the liquid (and thus determine if liquid level is too high/low). The two companies say that the hardware provides ...
