I'm new to circuits, Arduino, and programming. I'm trying to create a prototype for an idea of mine that requires controlling 4 separate coin vibrating motors through 1 program. As I'm in the early stages, I'm just trying to understand the basics of the circuit required. I'd like to use my Arduino UNO R3 and breadboard. I have successfully created a circuit powering 1 3.3V coin motor (did not use any MOSFET or progamming to control functionality). However, I'm not sure how to handle incorporating 3 more coin motors into the circuit. I need to be able to write a program that will turn on specific coin motors and control their individual vibration intensity/timing (I'd like them to pulse at a controllable speed) depending on external information that will be fed into the program. Can anyone share any advice or resources to help me get started?
I appreciate your help!
