Basically the title. I was hoping to use the ones I’ve linked instead of some kind of noise maker. The thing is, I have 3 of the TTGO T-Beams and am not sure if they put out enough current/power. Sorry if this has been asked before. I’ve done my best to use the search function but can’t find anything related.
DC Coreless Motor Built-in Vibration Waterproof 1.5-3v
For a start. Can simply be a resistor from GPIO output to the transistors gate( around 5k to10k). The transistor source connects to ground. Your device connects between + power and the drain. I have done this with an LED + resistor for PWM control. Your motor should only require a ceramic capacitor between the motor leads. About .001uf at 25 or greater volts. Larger inductive loads require diodes and other suppressors.
