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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
