I’ve had a bigger doorbell project planned for quite a while but 2 weeks ago decided we should do a simpler Halloween one. Using various bits bought from Sparkfun and Maplin along with a great tutorial from Adafruit, I finally got something we were happy with, working late last week. Then yesterday evening I put it in place on the door. Unfortunately, with all the pulling, taping and general movement, one of the five buttons stopped working. But the other 4 were fine.
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.
