The cardboard lamp will create a colourful ambient light most of the time, and when the button on the Circuit Playground Express is pressed, a light-and-sound countdown procedure will begin.
This would be a great project to do with kids – there’s no soldering required, and the most dangerous tool you’ll need is a craft knife or pair of sharp scissors. There are also lots of possible software or hardware extensions, so you can take the project wherever you like.
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.
