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” things of Microcontrollers and their ADCs - Look at different external boards and their usage I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.

How should we connect devices to our home network? Wireless or wired via Ethernet? Do these new POE boards from TTGO and Olimex change anything? Interesting questions. Let’s have a closer look. We all know: Wireless IOT devices are cool. But they have some drawbacks. This is why we want to look at the alternative: Wired IOT devices I am a proud Patreon of @GreatScott! , @ElectroBOOM , @Electronoobs , @EEVblog , and others.
