What would be a good method of controlling low AC voltage with an Arduino
I have an old motor (Lionel Postwar Train Motor from 1956 example) that runs on AC between 5vac and 18vac with a max of 8amp
I need to be able to manipulate the voltage with the Arduino so I can gradually increase or decrease it. Preferably as a percentage (0% = 0vac > 100% = 18vac) or decimals
So just to clarify. The power coming to the Arduino is already transformed at a constant 18vac.
I just need to safely control the voltage
Thanks
