**Motherboard for LittleBOT.**
LittleBot is a small robot equipped with a control card with an Arduino Nano. The chassis is made of aluminum and is moved by two small motor-driven motors made entirely of metal that move a pair of tracks.
The robot has some sensors that allow it to detect some parameters including brightness and temperature. A front-mounted sensor powered by a servomotor allows t...
Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials.
The soil moisture sensor is pretty straight forward to use.
The two large exposed pads function as probes for the sensor, together acting as a variable resistor.
The more water that is in the soil means the better the conductivity between the pads will be and will result in a lower resistance, and a h...
