Sep 11, 2021 · remove the jumper, and connect relay power to JD-VCC(+) and GND(-) of the relay module. Most powerbanks switch off with the light (50mA) load of an Arduino. Don't forget the snubber circuits on the mains side of the relays, otherwise you could have lockups and restarts of the Arduino.

In this guide, I’ll walk you through controlling an 8-channel relay using an Arduino Nano. This setup is great for automating multiple devices or systems, such as home automation, robotics, or industrial applications where switching multiple components is essential.

Learn how to wire an 8 relay module with this detailed diagram and step-by-step instructions. Expand your knowledge of relay wiring.

Jan 15, 2019 · We make a brief introduction to the relay module and build a simple project example with the Arduino. The example we’ll build shows how to control a relay module with an Arduino and a PIR motion sensor. By the end of this tutorial, you should be able to control any electronics appliances with your Arduino using a relay module.

Connect the signal terminal IN4、IN5 of 8-channel relay to port 17,18 of the Raspberry Pi, and connect an LED at the output terminal. （Pay attention to that there are only two submodules of the 8-channel relay are used in this example, but you can use the 8 submodules freely.）
