Thanks for the ATmega32U4 Breakout Board and TPIC6B595 chip. They are super! I am using them to learn basics. I always write a blog entry about what I learn. This way I am forced to learn the details and remember things better. Currently learning about shift registers and SPI.
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.
