Male peacocks shake their brilliantly-hued, long tail feathers to attract females in a courtship display known as “train-rattling.” But scientists had never closely examined the biomechanics behind this behavior—until now. A new paper in PLOS One concludes that the frequency at which those feathers vibrate can enhance this iridescent display—even as the eyespots remain almost perfectly still.
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.
