He wanted to do a little more with the equipment so he ditched the watch and built an Arduino-based heart rate monitor ... it will pulse an output pin with each beat of the heart.

Here's a good one, showing you how to build a heart rate monitor using a Genuino 101 with Bluetooth comms. The project takes advantage of the Bluetooth Smart comms (aka Bluetooth Low-energy) built ...

The $200 Bose SoundSport Pulse have thick, almost quarter-sized backs that are bigger than the buds themselves. This design is typical for all of these earbuds, since the heart rate monitor has to ...

Unlike an ECG (electrocardiogram) that reads electrical activity, an optical heart rate monitor detects the pulse by shining ... And whether it's programming an Arduino-controlled lighting system ...

System-on-chip (SoC) and integrated module solutions are rapidly replacing discrete, multicomponent designs. The MAX30102 integrates red and IR LEDs to modulate LED pulses for oxygen saturation (SpO2) ...

You may be interested in a project published to the Hackster.io website earlier this year providing instructions on how to create a simple wearable heart rate monitor using an Arduino Nano R3.

The build combines an EmotiBit sensor platform with an ... From this data, a pulse rate can be derived, and the LEDs flashed with a heart graphic in concert with the rhythm of the wearer’s ...
