That table top fan you have next to you is more interesting than you think! I took mine apart so I could show you how it works. The “four speed mechanism” releases any other button that was previously pressed down. Once a button is pressed a signal (voltage) is sent to the motor at the top of the fan. The oscillation motion is produced through the 4 bar mechanism. The last part of the video covers the gears that turn the 4 bar mechanism. The pin is part of the gears – when it is lifted the gears don’t connect and the fan will no longer oscillate back and forth.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
