First time posting anything like this but this is the first instrument music I've ever made and I have to get better at not being scared about sharing my art.

Coming soon - Soil sensor gets a square wave update

After pondering the Multi-Year Soil Sensor Thread over at https://zerocharactersleft.blogspot.com/2011/11/pcb-as-capacitive-soil-moisture-sensor.html we decided to make another prototype of our revised I2C soil sensor, this time we'll use the square wave filtering technique rather than the RC-rise-time system. We need a few more components to rectify/average the square wave signal, this is our rough draft. on the attiny816 we might be able to generate a 5 or 10MHz square wave. we also moved the AHT20 to be on a second set of pins we'll bitbang to read the temp/humidity. That way we can chain multiple sensors if desired.
