The main player of this project is Raspberry Pi 3 b+. There isn't much to say about this guy but I had few laying around the house from previous school projects ended up using one for this project. The problem is that both the Pi and the driver board need a power input of their own so there would be two wires that would need to be plugged in for the computer to work. Pi needs a 5V-2.5A input and driver board needs 12V-750mA to operate. In order to make use of only one power supply, I did a bit of calculation using the voltage divider formula. I chose my primary input to be the 12V supply and from there I can choose R1 and R2 so that my output voltage or voltage across R2 = 5V. Unfortunately, Pi has an internal resistance that is in parallel with R2 and this created a big problem. I can no longer use the voltage divider unless I choose my R2 to be the resistance of Pi and choose R1 accordingly. Doing this resulted in a very low current which was below the required minimum of 2.5A.
