The functioning “prototype”. (It) still needs wood fascia, dial bezels, glass and proper Speedo needles – the ones fitted are carved out of a piece of wooden clothes peg.
It has a Real Time Clock with a button cell battery to keep the time so that the clock hands automatically reset to the correct time at power up. It also automatically compensates for daylight savings time and advances and retards the hour on the appropriate dates and times.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
