We will be using the Flask framework (
http://Flask.pocoo.org/
) to deploy the web
server on Raspberry Pi. We made use of the Flask framework in
Project 4
,
Christmas Light
Sequencer
. Just in case you skipped through
Project 4
,
Christmas Light Sequencer
, a Python
package manager such as
pip
or
easy_install
is required to install the Flask framework:
sudo apt-get install python-pip
Ater the installaion of the Python package manager is complete, the Flask framework may
be installed as follows:
sudo pip install Flask

for-python
)
to take input from a browser:
In the frontend of the web server, let's create textboxes in the
form_
submit.html
file where we can enter the blood pressure, oxygen
saturation levels, and pulse data. The landing page will look like the
