ESP32 has 12bit of ADC as per datasheet. so it can measure the change of 12mV on ADC line I am trying to read 65mV on ADC lines.but it still gives 0. what is the minimum ADC input voltage range on ADC line of ESP32. See the post I made right above yours. Its around 100 ...

有个神奇的地方,ESP的芯片有专门控制LED的外设,又因为控制LED就是控制的PWM,舵机的控制也是PWM,所以很自然的就会想到用LED的外设去控制舵机。 可以参考官方的文档 LED 控制 (LEDC) 外设主要用于控制 LED 的强度,但也可用于生成 PWM 信号以用于其他目的。它有 16 个通道,可以生成独立的波形,例如用于驱动 RGB LED...
