Do I need resistors for a vibrating mini motor?

Post by Dougmeister »

Vibrating Mini Motor Disc
Product ID: 1201
https://www.adafruit.com/product/1201

Running these from a Pico, so 3.3v input. Circuit goes to one of these motor discs, then to one of these LED buttons:

Arcade Button with LED - 30mm Translucent Clear
Product ID: 3491

Question: do I need a resistor between the 3.3v from the Pico and the vibrating mini motor?

The LED button has a built-in resistor, so I'm good with that part (I think). Thanks.

Are you powering this from the 3.3v pin on the Pico? Or are you trying to run it from a GPIO pin?

You can power it directly with 3.3v - no resistor is necessary. But trying to drive it from a GPIO pin will likely damage the pin.

Yes. We tied the mini vibrating motor into the "button press circuit", which is powered by the 3.3v pin of the Pico (via a "+" rail on the breadboard at the moment).
