A couple of years ago I wanted to try out some iot-related stuff. I bought a couple of Arduino-boards and some random components and started fiddling around. At first I started out by trying some experiments such as temperature controlled LED lights and blinking stuff that reacted to sound. After this I wanted to get my feet wet and actually build something, preferably geeky, not necessarily very useful. Binary clocks have been an interest of mine for years. They kind of force you to take a step back and reflect on time, what time is, what is time and so on, and maybe slow down the frantic pace of modern life for a few seconds. Or not, but I like them anyway!
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.
