Two axis heliostat control using stepper motor

I am looking for a freelancer who can assist me in developing a two axis heliostat control system using a stepper motorb in arduino. The project requires moderate accuracy, with the heliostat control within 5 degrees. The sun position angles (azimuth and elevation) are already derived using another Arduino code. You have to use the angles from my Arduino code.

Skills and Experience: Arduino,
- Intermediate level programming language skills in C are necessary for this project.
- Knowledge and experience working with stepper motors, specifically unipolar stepper motors, is required.
