An electric tambourine that is completely powered by the playing of the instrument. Yellow LED lights on the jingles light up when the corresponding piezo is rattled. The harder the tambourine rattles, the greater the voltage generated by the piezoelectric elements and thus the brighter the light. If the tambourine is rattled with enough force, blue and red LED lights on the band also light up. Thus, the player can both hear and see the music generated by this instrument – by Jie Qi.
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.
