The “DOIT ESP32 DEVKIT V1” module has multiple ACD pins which work in range of 0V to 3.3V with 12 bits resolution (0-4095). The pin that we have used for this project is GPIO33 (D33). In the “ESP32 WiFi Microphone” project, we have used this channel as the audio signal input. Here’s the project link:…

The high voltage (parallel) programming method which has been used in WiCardKit Software programmer is the highest layer of access to the microcontroller memories and programming. This method can unlock the AVR/PIC chips which can’t be programmed by regular programmers while the chips work well. The other feature is the “reset” pin in some the…
