Project 1 – Selecting a project battery capacity

In our next chapter, we will begin building a robot line follower, and we know the Pi will need to be mobile and battery powered for this. Let's define what needs to be powered and just how big (mAh) our battery needs to be. First, let's lay out the specifications:
