# Exercise Buddy: Motion aware BLE media controller ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/108/956/medium800/sensors_DSC_0624.jpg?1644711308) Watching a riveting show while on a stationary bike is a good way to motivate yourself to exercise more regularly. There was even a scientific study done about it, which coined the term [“temptation bundling”](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4381662/ "“temptation bundling”"). But sometimes, the show might get way too interesting and you might not even notice that you've stopped cycling! This project creates a device that can detect simple movement, and when it detects that you've stopped moving, it will pause any videos or music playing on your Apple mobile device (iPad, iPhones, etc.). It's an exercise buddy that will remind you to keep moving so you can keep watching! ## Parts ### Adafruit LED Glasses Driver - nRF52840 Sensor Board [Adafruit LED Glasses Driver - nRF52840 Sensor Board](https://www.adafruit.com/product/5217) This board is designed to be a thin, Bluetooth®-enabled driver board for our [Adafruit LED Glasses](https://www.adafruit.com/product/5210) RGB LED matrix.
