In this week’s arduino tutorial, we take a bit of a detour and focus on some key elements of electrical engineering design that we’ll be using in future episodes. Included amongst these topics is Ohm’s Law, current-limiting resistors, pull-down and pull-up resistors, voltage dividers, potentiometers, analog inputs, and voltage regulators.
If you’re yearning to learn more after watching this video, I’d suggest you check out Jeri Ellsworth and Dave Jones on youtube. They offer videos about everything from circuit design to pinball machines.
