Need help powering Dc vibration motor with external battery
Hi, im making an irl recoil machine type thing where whenever i press left click (shoot) in a video game my dc motors starts spinning, creating vibration. I have a simple circuit right now, but when i try it with the bigger motor the arduino itself doesnt give enough power to make it spin. So i have to add a battery and at this point i dont really know what to do except from that a mosfet might be good to use. This is the circuit i have at the moment. If anyone could help me build a circuit or give any ideas that would be very appreciated
