We’ve all seen hamsters in a cage, furiously running nowhere. Perhaps you’ve thought about the pointlessness of this activity, before going to the gym to lift weights up and down or run on a treadmill. From an outside perspective, both activities seem pointless, but when you realize the benefits, maybe tracking what “feats of strength” you’re able to accomplish, things become much more clear.
As seen on Hackaday, in order to track the activity of his daughter’s hamster, John Mueller implemented an Arduino Uno-based system that records revolutions using a magnet and a reed switch. Every time the magnet on the wheel passes the fixed switch, it triggers an Arduino input, recording how many revolutions, and thus how many miles the little guy runs each night. Results are quite impressive considering its size, recording over 3.5 miles on one occasion!
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.
