Schematic PDF

### The repository does not contain a schematic pdf for quick review by anyone who wants to start the project. The kidcad software will have to be installed before one can view the schematic or the developer will have to checkout the readme file for the schematic.
Suggestions:

- [ ] The schematic should be saved in an output folder together with the bill of materials (BOM) and Gerber files.
- [ ] The schematic should be saved as a PDF file so that it can be easily downloaded and read by developers.
- [ ] The schematic should not be squeezed onto a single page. Instead, the blocks of the schematic should be divided into multiple pages.
- [ ] The schematic should be drawn according to best practices, such as having the ground ports pointing down and the positive ports pointing up. This will ensure a logical flow when reading the schematic
