Part 4 – Schematics, Ohm’s Law and Potentiometers

Part 4 is where we started to get into more complicated circuits. The first part of the lab laid out some of the notation used to communicate these circuits. First, we tested the circuit we built from part 3 with a different wiring, which didn’t work. Next we moved on to testing LED brightness using different resistors. Which one was brightest, the with the least resistance of course, the 100ohm.

Part 1 – Intro to Soldering and Building Power Supply

This is the first post for my Mt. Sac class Electronics 10 Mechatronics. In this lab we got to play a bit with some of the basics of electronics.

The lab is divided into two sections, learning how to solder (which I’ve done a lot of in the past, even though you can’t tell from the quality I exhibit below), and then applying that soldering technique to building the power supply I will use for the remainder of the class.
