Have you ever been on a swing set and suddenly noticed that the person on the swing next to you seems to be swinging almost exactly in time with you? You go up and down at either the same time or exactly opposite each other. This might seem random—but it’s actually physics! Like many things in nature, swing sets have a resonant frequency, which means they have a “favorite” frequency (or speed) of movement. The swing set will naturally want to swing at its favorite speed. You might have experienced this if someone has ever tried to push you too fast on the swing; the preferred speed can actually make you go slower.
Each Tuesday is EducationTuesday here at Adafruit! Be sure to check out our posts about educators and all things STEM. Adafruit supports our educators and loves to spread the good word about educational STEM innovations!
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.
