Hello. I am new to using the Circuit Playground Express and am working on this project to detect soil moisture: https://learn.adafruit.com/sensor-plott ... l-moisture
Every other test prompt using this setup seems to work (sound, temperature, etc), however, using the alligator clips and nail, I am unable to detect any soil moisture levels on the CircuitPython plotter. Without this, I can't calibrate the levels to finish the project.
Does anyone have any advice on updating anything, or using a different nail or any indication why the levels wouldn't appear? The plotter is simply still.
Thank you!

Re: Circuit Playground Express Soil Sensor - no plotting
For anyone else who comes across this, here was the problem:
The version of CircuitPython for Mac that I downloaded did not have the simpleio file. That version is recommended for beginners, but seems to be missing some files. I went to the github version of the download, pulled simpleio and added it to the lib folder. After that, plotting works.
