How good are the ADCs inside Arduinos, ESP8266, and ESP32? And extenal ADCs (ADS1115)

I often get questions about how to measure voltage with microcontrollers. We will look at this topic, at the quality of built-in and external Analog-to-digital converters, and I will show you some “secrets.” In this video, we will: - See how ADCs work - Look at how we can determine the quality of ADCs - Compare the ADCs of different microcontrollers with external chips - Learn how to tweak the calculations to get the best out of any ADC - See how we can extend the range of ADCs - Discover some “hidden” thin
