Funduino Relay Board Wiring. PIR motion sensor set as an input pinModePIRInterrupt INPUT. After so many hours I am totally lost.
The active wire is connected to Normally Closed and common int relay 8. Connecting multiple input devices to 8 channel relay board. PIR motion sensor set as an input pinModePIRInterrupt INPUT.
The setup is fairly simple just make sure that the high voltage connections to the relay are secure.
PIR motion sensor set as an input pinModePIRInterrupt INPUT. On the edge of the board are many pins with whom it is possible to connect different components. Connect the side leading to the light bulb to the NO terminal of the relay and the side leading to the plug to the C terminal. Each relay is switched onoff by an opto-isolated digital input that can be connected directly to a microcontroller output pin.
