This photo below is our photo of our set-up of our artificial pancreas. This set-up has a breadboard, 1 pump,2 tubing, 8 batteries, 2 plastic containers with vinegar and baking soda respectively.  A potentiometer , a N-channel mosfet and a container with neutralised solution. 

Our Artificial Pancreas at work

We have to go through what our experiment is doing. My group is doing the artificial pancreas. We are using baking soda, vinegar and a neutralised solution.So we measure the pH level of the neutralised baking soda and vinegar.  We are attaching the pump to the baking soda and vinegar. So  solution is connected to the breadboard. So the neutralised solution is the standard Ph level. Then, we are going to pump the baking soda into the vinegar. Thus the Ph level of the vinegar will become the Ph level of the neutralised solution. The breadboard will determine when the pump will stop.
Finding the Ph level of vinegar.-4
Finding the Ph level of neutralised solution(vinegar and baking soda with water)-7
After the experiment we are take the Ph level of the vinegar now with the baking soda.

The table below shows our table of our results
