The Arduino software was actually based in part on ”Processing” open-source. Once Processing is installed, open processing. To download “Processing”, go and download the latest version for your operating system. To listen in on what the Arduino sketch is sending, Processing is used and comes with a Serial library designed for it. This processing runs on a computer that is communicating serially to the Arduino processor that is getting analog input from the pulse sensor as input. Processing: The Pulse Sensor comes with code for on screen processing. PURPLE wire = signal (analog pin 0 - in Arduino code)Īrduino code designed to fade an LED on Digital Pin 5Īrduino code designed to Blink pin 13 with pulse ![]() Pulse Sensor PURPLE wire goes to Analog Pin 5Īrduino code designed to fade an LED on Digital Pin 11Īrduino code designed to Blink pin 13 to a LED with the pulse. Plug the Pulse Sensor into Power (RED wire = +3V to +5V), Ground (BLACK wire), and Analog Pin 5 (PURPLE wire = signal). PURPLE wire = signal (analog pin 0 in Arduino code) Test using the LEDs and an Oscilloscope while using your own pulse. Wire the Arduino to the Pulse Sensor and to two LEDs. Upload the Pulse Sensor sketch to the Arduino Install the Arduino sketch software on a computerĭownload the sketch for the Pulse Sensor from the internetĭownload and install the processing code to your computer from the internetĭownload and install the Processing runtime software to your computer from the internet The processing is using “Processing” software that runs on a computer. My project uses an Arduino with built in analog and digital I/O, two LEDS two resistors, USB serial communication, and heart pulse sensor. Of course Arduino example code is available as well as a Processing sketch for visualizing heart rate data. Simply clip the Pulse Sensor to your earlobe or finger tip and plug it into your 3 *or *5 Volt Arduino and you're ready to read heart rate! The 24" cable on the Pulse Sensor is terminated with standard male headers so there's no soldering required. Also, it sips power with just 4mA current draw at 5V so it's great for mobile applications. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects.It essentially combines a simple optical heart rate sensor with amplification and noise cancellation circuitry making it fast and easy to get reliable pulse readings. The Pulse Sensor Amped is a plug-and-play heart-rate sensor for Arduino. Luckily, the Pulse Sensor Amped can solve that problem! The problem is that heart rate can be difficult to measure. Heart rate data can be really useful whether you're designing an exercise routine, studying your activity or anxiety levels or just want your shirt to blink with your heart beat.
