MCU

arduno nao

Ardonu Nano

The classic Arduino Nano is the smallest board to build your projects with. Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms.

control board

The control board is composed of two switch button connecting to the MCU.
