How to interface or connect the starter relay with arduino Pro mini?
They do sell contactors that use 4-6V for control. That would work for 5V Pro Mini. It would not work for 3.3V Pro Mini.I assume the reference to starter is a Contactor?
If so, they can be obtained with AC or DC coils of various voltages.
If using DC then a logic Mosfet could be used.
Use a reverse EMF diode across the coil.
Starter relay is automobile relay used in two wheelers. I can connect this starter relay with arduino Pro mini 5v for one of the road safety project.They do sell contactors that use 4-6V for control. That would work for 5V Pro Mini. It would not work for 3.3V Pro Mini.
Yes you can... by controlling a properly rated MOSFET.Mosfet is OK but, I can control the starter relay within the bike using arduino for my project.
Do you want the specs of a MOSFET that will work. Not meaning to speak for the others, but we have no clue... You have to get the relay operating voltage, the current it draws when activated, the supply voltage (and source) for the Arduino and relay... You haven’t supplied and of us that information.Mosfet range?
