Hi all
Background I have an old motorcycle with an ignition point. I want to switch to the CDI and the pickup coil in the ignition position with microcontroller (arduino) but I do not know how much pickup coil generate ACVOLT?I want to build a circuit to receive the signal from the bike pickup coil, but I have very little knowledge of electronics.Please help me with the design. And explain the function of the circuit.I like electrons and ready to learn.
