1, DC +: positive power supply ( voltage required by the relay , there 5V.9V.12V and 24V choice )2, DC-: negative power connection3, IN1-IN4: each way based on the settings , can be high or low to control the corresponding relayRelay outputs...
Follow the connections in the first picture. Using male to male jumper wires connect the servo ground (black or purple) to the ground on the Arduino board, the power wire (red) to the 5v pin, and the control wire (yellow or orange) to pin 9 on the board. Open up the Arduino IDE ...
You know as well as I do that when tinkering around you suddenly get a new idea and need x or y :-DAuto shutdownWhen the engine is running and charging the car battery the incoming voltage used to power the board is a little bit higher than when the engine is stopped. This can be...
