So I have an Adafruit Circuit Playground Express board to play with. This project seems like a good way to learn Circuit Python programming and to get more familiar with the Mu Editor and REPL function.
The board is capable of driving Neopixels which are the LED strips I have encased in the traffic light shells. I have two strips of 11 Neopixels respectively attached to pins A1 and A2 of the board. I am also getting the hang of making those connectors used to connect the Neopixel strip to the board wires. They are called Dupont connectors – female header socket/ male pin similar to those found on jumper wires used for breadboarding. Getting the pin crimp done just right with the crimping tool takes practice.
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.
