In Module 3.3, we learn about how analog to digital conversion (ADC) works and what the terminology actually means. We learn about ADC resolution and bit-depth, sampling rates, and things that can increase or decrease the accuracy of our ADC. Finally we use the internal ADC on the Wildlogger board to measure our battery voltage which will eventually allow us to track our battery levels on the datalogger. By the end of this submodule, you’ll know the difference between a 10-bit ADC and a 16-bit ADC, how to interface sensors to them, and how to write software to read and process their data.
If you have questions while working through this module, you can ask your question in the Module 3.3 forum thread here.
Coming up in Module 3.4
We'll learn about quartz crystals, how temperature affects clock drift, and use a library to set out date and time using the command line.
