How create a detailed motor controller using an arduino motor shield with the uno?
Hi, i'm new here and new to the arduino. I am using an arduino motor sheild and the uno board to contol a 4v dc motor. I want to be able to make the motor spin forward as well as reverse the polarity and make it spin in the opposite direction. Also using four inputs, preferrably push buttons, I need it to increase the motor speed by 5%, decrease the motor speed by 5%, make the motor speed 25% of max speed and make the motor speed 50% of max speed. Code examples would be really helpful. Your time and help are greatly appreciated.
