Why?
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
In order to build a power cutter using a relay module, one must follow the circuit provided.
It is the required hardware:
- 1 BJT transistor 2N2222A
- 1 3.3 kOhms resistor
- 1 1N4007 diode
- 1 relay module (RAS-0510)
- 1 Protoboard or perforated PCB (min 4.5x4.5 cm)
- 1 Two positions terminal block
- 1 male outlet connector and 1 female outlet plug
- 14AWG Wire (as needed)
