Relaxino – the Arduino-based relaxation device

If work is getting to you, or at the end of the day you just can’t relax – consider making yourself a “Relaxino”. Created by Arduino forum member “trendski”, it’s a biofeedback device that can detect your heart rate using a clip-on ear sensor. As the system detects your heart beats, it displays whether your heart rate is above, below or just around a certain level with LEDs – thus giving you a method of focusing on and reducing your heart rate. 

If you decide to make such a device, ensure you power the system from a battery and not the mains power. For more information and the sketch, click here to visit the Arduino forum post. And for more, we’re on twitter and Google+, so follow us for news and product updates as well.

When creating projects with external circuitry hacking existing devices – consider our range of ProtoShields. From the tiny LeoStick to the Mega range, we offer a complete range for you to work with
