Exercycle App

In the root directory of the project, simply run:

python run.py

---

This is the app-portion of my DIY exercycle project.

The website displays count, speed and history in realtime.

Uses:

1. express-js - simple, fast webserver
2. pyserial - for talking to the Arduino over serial

Pitfalls / Lessons Learned

1. I found nodeJS unsuitable for reading from a serial: there's a great library serialport, but sad to say, javascript Promises defeated me. Specifically I was unable to call SerialPort.list() because its async. And I couldn't find a way to delay calls to read, so that I don't get broken data.

2. When accessing a COM port on Windows, no other app should be using it. So close any arduino IDE / processing windows.

2. Debugging "access denied to port"
3. python Popen runs in background
