1 | # Pulse-Project
2 | I used a combination of tools to build a website that displays my heart rate in real time
3 |
4 | I used a pulse sensor, an Arduino, and a Raspberry Pi to create a website that displays my
5 | heart rate in real time, and I used a tunneling service called "ngrok" to expose my local
6 | address to the internet.
