Today for Hour of Code check out some of these lessons from Texas Instruments. The activities are designed for the ubiquitous graphing calculator. There was a time when these were the most sophisticated piece of technology in a classroom.
There are a bunch of lessons on the site tailored to all skill levels.
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.
