Quick and dirty web server that forwards temperatures to an Arduino board driving a peltier element.
python -m venv .venv
. .venv/bin/activate
pip install -r requirements.txt
flask run
Let's assume the server is running on mylaptop.local. Then you can send (from anywhere on the local wifi network) an HTTP GET request to http://mylaptop.local:5000/peltier/37.3.
The server will print a message Temperature: 37.3 and forward the request to the Arduino board over a USB serial connection.
