28BYJ-48-5V Scara Bot

As a small project, i tried to put a scara bot together with the idea of 3d printing with it. While the accuracy of this bot is good, there is too much backlash. I included the inventor files, STL files, a photo of the working project and the arduino code that makes the whole thing work.

Needed for this project:
- Arduino with 8 digital pins
- 4x 28BYJ Stepper
- 4x Driver board ULN2003
- Some nuts & bolts
- 4x 623ZZ Bearing
- 4x 608ZZ Bearing
