Kevin Sidwar made a great blog post targeted at someone without much electronics experience and explaining how common communication protocols for microprocessors work. This is a great post to check out to understand things like the difference between SPI & I2C, or what kind of speed you might expect from various protocols. Check it out for a clear explanation of different protocols you’ll find on boards like Tessel, Arduino, Raspberry Pi, and more.
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.
