Time for part 4 of the tweet-a-watt (the project formally known as ‘wattcher’) design documentation! In this section, we play with the Google visualization widgets to save us lots of time. I will show you how to take data from the Google App Engine datastore, turn it into JSON and then make it visualization-happy for nice Flash graphs. The code is also fully available in a google code repository so hopefully people with better software skillz than I can submit patches and help out.
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.
