This is an Arduino based iPod hackaudio project that allows you to select tracks for playback from an attached iPod Touch simply by placing cards on flat upper surface of the machine.
The cards can be placed in small plastic boxes with a picture of the album cover on one side to make small blocks more suitable for small hands to manipulate. Originally designed for disabled child. Since then people, teachers I know and so on, have been urging me to “do something with it” so this is an easier to set up and use quasi “tablet” version.
Membrane Matrix Keypad + extras – 3×4— Punch in your secret key into this numeric matrix keypad. This keypad has 12 buttons, arranged in a telephone-line 3×4 grid. It’s made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly anything. The keys are connected into a matrix, so you only need 7 microcontroller pins (3-columns and 4-rows) to scan through the pad.
We include a 7-pin extra-long header strip so you can plug this into a breadboard with ease.
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.
