Ab 11 Pin Relay Wiring Diagram. Fuel injector 2 10. One side of the main efi relay coil should be connected to this pin and one side of the main efi relay coil should be connected to ground.
Arduino 5v pin relay module vcc pin. The ldr circuit diagram works like this. Setup motion card hardware 4.
The iso mini relay we have looked at above has 4 pins or terminals on the body and is referred to as a make break relay because there is one high current circuit and a contact that is either open or closed depending upon whether the relay is at rest or energised.
Using the arduino we can connect the wires and send signals to activate the relay switches. E ub or eub. Working and schematic diagram of clap swith circuit. Arduino 5v pin relay module vcc pin.
