Ledc fade too fast

NettetThe LED control (LEDC) module is primarily designed to control the intensity of LEDs, although it can be used to generate PWM signals for other purposes as well. It has 16 channels which can generate independent waveforms, that can be used to drive e.g. RGB LED devices. Half of all LEDC’s channels provide high speed mode of operation. Nettet6. mai 2024 · When trying to modify the examples to fade over a long time I get a stepping effect on the low levels of light, about 0-100. The resolution of the PWM is too coarse. This is a hardware problem because the arduino PWM is integer based. You have to change your hardware and use Mosfets to sink the current and use the PWM to drive the mosfets.
