I am yet to have my very own Arduino but will be getting one shortly. I would like to be able to use a standard type (what ever that may be) automotive fuel injector with the arduino.
I see that you can use a SSR-solid state relay. Is this the general normal practice that would be in a cars electronics? There was a thread about inductance with motors and SSR’s and you need to have a resistor in there to prevent something from happening?
Does anyone know what the requirements are of a fuel injector? Like how long can you keep it energized with 12 volts for? Will it draw too many amps and break etc?
I assume a standard arduino would be fine for the task. It seems like you can just send the arduino logic level signals to one side of the SSR and then have a 12v battery hooked up to the other side circuit for the injector?
