Justification?

The Arduino Single power control unit was created for controlling a relay that is able to turn on/off the devices that it powers like the Yocto DUTs. Such need has arisen due to a clean power-off is not always reliable.

The software part

The hardware part

The circuit

In order to build a power cutter using a relay module, one must follow the circuit provided.
