Honestly, there is no better motivation for keeping up with exercise than taking classes, but not many people have the discipline — or the pocketbook — to keep going to the gym for the long haul. With this in mind, [Jason] looked for a way to control PS4  games like Mario Karts or TrackMania with his recumbent bike. In an attempt to avoid modifying the bike, [Jason] decided on a wearable motion sensor for his ankle. Consisting of an Uno, an MPU9250 accelerometer, and a transmitter for the 433-MHz ISM band, the wearable sends signals to a receiver whenever the feet are moving.
