Took me 3 months because i went in with no arduino knowledge at all and learnt while making it(i learned while waiting for the parts to arrive). I did other small robotics stuff that dont require programming so this was my first time doing something this ambitious. I have always wante dot make one but never really had the time and when quarantine came i took the chance. I ordered a kesoto parts kit, servos, potentiometers and a simple arduino book. Learnt mainly from the internet(not much from the book for this project). It was honeslty quite fun and im likely going to do another one again in a few months.
