Firstly, I have a very limited amount of funds for something that I only intend to be a fun project.

Funds Already Spent for Resources
Arduino kit = $50-$90
Lego Pieces (that I cannot find in the house) = $35
Arduino Online Course (thank you Udemy sale) = $10

Readily Accessible Resources
Arduino DYI Books and Online Tutorials
MAG Hackerspace LAB
Programming Software

What I need to learn
Arduino Systems
Soldering
C++ (can't be too different from C, right?)
Robotics fundamentals
