Thanks to this nice tutorial http://ladyada.net/make/solarlogger/ I’ve done a substantial upgrade! Now I can monitor and save the following data:
Voltage: Panel, Battery, Load
Current: Panel and soon battery (waiting on parts)
Temperature: battery, in case it gets too hot.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
