Awww, You make me blush. Wouldn’t it be cool to animate your Adafruit Circuit Playground electronic component plushie? I have Ruby the Red LED plushie. I wanted it to light up and have it respond to sound. Here is an easy mod to get that done. Sorry, no lasers this time.
Probably wouldn’t really be considered old-school soft circuits but probably more of a hybrid, electronics in a softshell case. I still have a bobbin of conductive thread I need to do something with. Note that this was a first attempt in trying to do a mod with stuff I had on hand but I will offer suggestions on what you should do to get a more satisfactory result.
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.
