Light Relay with Arduino Nano | Electronics and domotica

Principles

Use a relay module to switch the mains for a LED light.
Use an Arduino Nano
The HLK-PM01 power supply is permanently on
The 230V AC of the LED power supply is switched by the relay module.

The result

Testing with 2 very bright LED bars

Used Components

An ArduinoNano5V based RFNanoKeywish which includes a NRF24L01+.
A power supply for the Arduino based on the PowerSupply_HLK-PM01.
A 12V DC 60W power supply.
LED bars 12V.

Wiring
