OK, so a while ago I fell in live with these Nokia 5110/3310 LCD displays. They use a library from adafruit.com that you can find here. They are small, fast, and don’t gobble up a lot of current. So I needed a project to make so I could use one. The result? A massive overkill of an LED controler with all kinds of options and features.
So I was thinking about a RGB to HEX Color converter that I had made for the 2.8″ TFTLCD, and the fact that I might want to figure out values without erasing my sketch I’m working on. Although it’s nice to see the color displayed on the screen it will end up on, sometimes you just need a quick answer. Thanks to brookware2000 (in the Adafruit forums), there is a nice small program here that will do the trick. But it runs on Windows, and I’m kind of a Mac guy. The answer? Build one into my nifty little box that already has 8 buttons, an RGB LED, and a nice LCD screen! So here it is.
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.
