Read the analog world: Use ADC's on Pi Pico

I explain how the principle (SAR) of the ADC (Analog Digital Converter) works in the Pi Pico. For this I use examples in Micropyhton for usw of ADC, temperature read out and how to read the V_SYS voltage. And i explain the electronics. In addition, I explain the limitations of the RP2040 used and the circuit on the Pi Pico. This is followed by examples of using a free ADC as well as the temperature and the V SYS voltage on the Pi Pico Board. Also i explain how to adjust the ADC reference voltage. ------------------------------------------------------------- Tools i use: Wires: https://amzn.to/3Etm4Nl * bread board kit: https://amzn.to/3PvUTrk * LED set : https://amzn.to/3P94pzo * transisotrs: https://amzn.to/44LrEVZ * Pi Pico W: https://amzn.to/467nAR3 * *affiliate link ---------------------------------------------------------------
