43 8 channel relay board circuit diagram
Circuit Diagram of the ESP32 Home Automation Project: This is the complete circuit diagram for this home automation project. I have explained the circuit in the tutorial video. The circuit is very simple, I have used the GPIO pins D23, D22, D21, D19, D18, D5, D25 & D26 to control the 8 relays. [Arduino Relay Diagram] - 9 images - 12v 1 channel latching relay module with touch bistable, 8 channel 5v relay module wiki, Circuit of the ESP32 Home Automation using IoT. The circuit is very simple, I have used D23, D22, D21, D19, D18, D5, D25 & D26 GPIO to control the 8-channel relay module. And the GPIO D13, D12, D14, D27, D33, D32, D15 & D4 are connected with switches to control the relay module manually. The output pin of the IR receiver is connected with GPIO D35. 8 channel relay board circuit diagram
