I recently held a workshop to teach students about e-textiles, and so I was looking for a cheap way to allow learners to make something that’s programmable, and that lights up and plays music. The instructions for the participants had to be easy to follow as well. I eventually came up with the idea of sewing a circuit onto a felt patch using a LilyTwinkle. Based on the ATTiny, the LilyTwinkle is a fraction of a cost of the LilyPad Arduino and can still provide good entertainment. The felt patch can be used as an applique onto any wearable you want. You can sew, hot-glue, or velcro it onto a sweater or pillow.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
