We’ve been working on a map of the United Kingdom, with a capacitive touch interface that you can touch to trigger an output that’s relevant to the point on the map that you’re touching. It’s still in its prototype phase, as we’re waiting for the price of hardwood to come down so that we can build a chunky frame to house the electricals, but for now, we’re hard at work creating a proof of concept.
For this purpose we’ve chosen the Adafruit Capacitive Touch HAT for Raspberry Pi MPR121, which is a snip at $14.95.
Now it’s time to make sure that we’re running the latest version of CircuitPython; Python may be as old as time, but CircuitPython is a relatively modern offshoot.
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.
