Nettet1. apr. 2024 · The maximum drive current from any GPIO pin on the ESP-32 is 12 ma. R = V/I, but I'll spell them out; Resistance = Voltage/Current = 3.3 v/12 ma = 275Ω. I can't find a part number on the piezo buzzer, but I've seen places that use 8Ω. 220Ω resistor with the piezo is a little low.

how to create additional desktop windows 10NettetThe LEDC output component exposes a LEDC PWM channel of the ESP32 as an output component.
