Update `readme.md` with information about banchs and libs

Add in readme:
- [x] Information and links about `Arduino` and `Vespa` branchs;
- [x] Information and links about necessary libraries;
- [ ] Add `Arduino` circuit;
- [ ] Add `Vespa` circuit;
- [ ] Overview of how the `Vespa` code works;
- [ ] Overview of how the `Arduino` code works;
- [ ] Put a version in Portuguese and another in English by a link to switch it;
- [ ] Put an image of the robot, one with Vespa and the another with Arduino.

Start with readme.md and review the Arduino and Vespa branches and the listed necessary libraries to understand what information is missing. Done means the README includes both circuit descriptions, code overviews, Portuguese and English links, and the requested robot images.
