Wear your heartbeat on your arm with the Beatband Sleeve. You’ll combine a pulse sensor with a DIY Arduino microcontroller (and a minty tin) to create this wearable pulse-blinking project. Connect the sensor to your body wherever you get a good pulse reading, and display your heartbeat on the five flashing LEDs. Wear it while you run, play video games, or even while you meditate to show your calming heartbeat ryhthm.
This project goes through several iterations of the circuit. First you’ll build a fully functional Arduino on a breadboard using the parts from a MintDuino kit. Then you’ll re-flash that circuit with the program for the Pulse Sensor. Finally you’ll transfer the circuit to perfboard and fit it all inside the tin for a fun, wearable project that slips into a sports armband.
Idea: instead of lighting all 5 LEDs always, light 1 if the heart rate is slow, and 5 when it is very fast, and in-between when in-between! If the time between now and the last heartbeat is t in milliseconds, then map(t,500,1200,5,1) give or take should do it… (500 ms = 120 beats per second, really fast, 1200 = 50 beats per second, very slow.)
@Steven Swift: I love this idea – especially with a series of different colored LED’s. As designed, all of the LED’s are connected to the Mintduino/Arduino’s pin 13. To make the LED’s blink as you described, you’d need to connect LED to a different digital out pin – perhaps pins 9 – 13.
Yes, exactly what I had in mind. Do it!
Is it possible to log your heart beat through serial communication? I am hoping to create an exercise task for my final project and collecting data from the heartbeat to measure
@Crystaltong18: You could definitely modify this project to log data over a serial connection. However, rather than running wires across a person, you might find it easier to use a data logging shield, log the heartbeat data to an SD chip, then review the data from the chip.
Hi
How did you program the Arduino Mintduino and Can you Upload the program for me please as I am new to Arduino pulse Into great in programming.
I’ve attempted at building this but once I’ve uploaded the code for the pulse sensor the green LED keeps blinking non-stop. What should I do?
beat band sleeve in block diagram available????????
