Via Instructables, Antoine7890 presents the Blinky KEY Board Soldering Kit.
This is Blinky KEY board, an electronic kit you put together to make your own LED blinking keychain! Everybody can build this project, thanks to these easy to follow, step-by-step instructions I made and a few simple tools. You will learn basic electronic components, and also how to solder to make something useful!
The board has 5 bright LEDs that blinks and display various animations! Powered by a single coin cell battery and the popular Atmel Attiny85 chip, you can create your own Arduino code to create your own animations!
The project is open-source and kits are available if you wish to get the parts rather than hunt for them.
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.
