As this project involved a sound understanding of celestial coordinates, we had to spend a significant amount of time looking at the stars. This involved an integration of hardware and software like controlling stepper motors using some keys on a GUI running on a computer. This time, my partners - Saloni (DA-IICT, Gandhinagar), Ram Mohan (IIT-BHU), and Jai Deep (NIT, Durgapur) - and I were assigned to work on an MHRD sponsored project titledĭevelopment of an affordable Open Sky Planetarium.

Naturally, another internship there, this summer, was like a dream come true. Use 1/16 microsteps mode to drive sidereal - also determines the LOWEST speed.An internship at IITB in 2015 left a lasting impact on my mind. Stepper drive have 200 steps per revolution
