This is a very simple Arduino shield with only one purpose: to Serve as a timer for practicing the Pomodoro Technique®. If you’ve never heard of this technique, you might want to have a quick peak at their site before reading on.What follows is fairly long winded. If you’re not all that interested in the process, and just want some links to the Arduino sketch, schematics and board layout, skip to resources section at the end.
I wanted very simple project that could be completed in a short amount of time and I wanted it to be useful. Since I am sometimes prone to fits of procrastination, I am familiar with the Pomodoro Technique® and find it to be a good way to help get things done. In my environment, the prescribed tomato kitchen timer is too noisy. So, a specialized pomodoro timer to use at work makes for a great, simple project.
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.
