We really like the Adafruit Trellis keypad, and realized that it would be a great Monome. Then it occurred to me…my daughter loves blinking lights and music, how cool would it be to make her a Baby DJ Monome for playing her favorite songs!
So we started with the Trellis keypad, then added an Adafruit Wave Shield. We stacked it all on top of an Arduino Uno R3, We won’t bore you with how to build these, just follow Adafruit’s excellent tutorials for the Wave Shield and Trellis. Here is a quick video showing the innards:
Next we 3D printed a case using Pumping Station One’s Makerbot. Adafruit has provided a nice guide on how to print a case for these. Ours did not turn out perfectly, but the result worked well for our initial prototype. Note we made our case a little taller than the Adafruit example since we had to also fit a Wave Shield.
Finally, we had to test our prototype on our favorite toddler. Turns out she loves it!
For the next iteration, we would like to incorporate a speaker and rechargeable batteries. It will make it a little bigger, but anyone with kids knows that wires hanging off will only cause problems down the road!
Next up, Craig will be showing off their products at the Chicago Northside Mini Maker Faire in a few weeks, lots of Adafruit will be there!
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

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.
