Arduino Programming
Arduino programming is about electrical stuff (M&E)
Science had been introduced like Current flow, Ohm's law, and all voltages in a circuit is equal to 0. V(cc)=V(resistance)+V(LED).
All this scientific stuff will affect how the electrical system works and how it is affected to each and every part of the system.
