Play the star spangled banner using CircuitPython and the Circuit Playground Express from Adafruit! I went to search for the notes to the song online and found that Ryan Aebi had already converted them to frequency in Hz , so he saved me a ton of time.
The board blinks the NeoPixels in red, white, and blue while playing, activated by pressing both buttons at the same time. Otherwise, it will just light up depending on the capacitive touch pads. Very clever!
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.
