Multiple vibration motors with Flora

by LorenzV on Sat Mar 06, 2021 8:57 am

I'm working on a bracelet with Flora and three vibrating mini disc motors. I'd like to build the bracelet as small as possible, with as few components as possible. Could I connect the motors directly to the pins without haptic motor controllers (https://www.adafruit.com/product/2305)?

I plan on wiring it similar to this bracelet that uses Gemma: https://learn.adafruit.com/buzzing-mind ... it-diagram

Thank you for your answers!

You've answered your own question :). That project controls a vibrating motor directly. The only thing a haptic controller gives you is vibration patterns. The motor is just that, a simple DC motor... apply power and it vibrates. You'll need a resistor, transistor, and diode for each motor (assuming you want to control them separately).
