Create an Exercise Bike That Won’t Let You Watch TV If You Don’t Pedal

Exercise is about finding motivation. This custom bike stand you can build at home will let you watch TV while you workout, but only if you keep pedaling.
You’ve probably already seen a bike set up to provide power , but this project from Instructables, which a user plays in traffic, does something different. Rather than supplying or disconnecting power, this setting simply mutes the TV signal after 10 seconds of inactivity. Resume pedaling and the signal will be restored. There is even a warning buzzer that warns you before the alarm goes off. The assembly uses a bike, bike stand, Arduino Nano, and a few other simple components, but the construction is pretty simple. Once you add it all up, the only way to watch TV is to work for it. This is a great way to motivate your exercises and keep you entertained at the same time. You can see a simple video of how it workshere .
