In this video I have shown you how to make your own 4 channel switch like sonoff. With this internet of things project, you can control 4 home appliances from Android smartphone and manual switches with push button. So this is a very useful homemade IoT based home automation system that you can easily make with NodeMCU, Relay Module, Push Buttons, and other electronics component.
Here are the components that you will need to make this project:
1 x PCB SwitchIoT 4CH (PCBWAY)
1 x NodeMCU Amica ESP8266
4 x NPN Transistor BC547
4 x Diode 1N4148
4 x Yellow LED 3mm
1 x Blue LED 3mm
8 x Resistor 1K Ohm 1/4W
1 x Resistor 330 Ohm 1/4W
4 x Tact Switch 18mm
4 x Relay 5VDC
1 x Hi-Link Step-Down 220VAC to 5VDC
2 x 15 pin Female Header
5 x 2 pin Terminal Block Screw
