ADC: On-chip 12-bit SAR (Successive Approximation Registers) ADCs (Analog to Digital Converter) which supports measurements on 16 channels of ESP32. DAC: On-chip two 8-bit DAC (Digital to Analog) channels to produce digital signals into analog voltage signal outputs. Both DAC channels can al...
The ESP32 offers a range of General-Purpose Input/Output (GPIO) pins, allowing digital signals to be read or output. These pins are crucial for interfacing with sensors, actuators, and other digital devices. The ESP32 has 34 GPIO pins in total numbered GPIO0 to GPIO39. Some GPIO pins ar...

If we assume that the default range of an ADC input is 0-3.3V then by applying these attenuation's, I can change the range to:ADC_ATTEN_2_5db - 1/1.34 - 0-4.4V ADC_ATTEN_6db - 1/2 - 0-6.6V ADC_ATTEN_11db - 1/3.6 - 0-11.8V...
Therefore, the average voltage of the waveform does also change and this creates some sort of controllable analog output (not exactly). The PWM frequency is just 1/T where T is the period of each cycle. You can set the frequency to any value you want depending on what you’re trying ...
