Day 2: Multimeters, Breadboards and Resistors

Today we learned about voltage, current and resistance.
We learned how to use a multimeter and how to properly verify the capacity of resistors through the use of resistor color codes.
We then learned how to properly power an LED and together with our new found knowledge of resistors, we put all these components together on a breadboard.
We learned how to use breadboards and how they are important to the everyday geek- i mean electrician/electronics person.
Breadboards.
No, they are not edible... they are plastic boards with many holes for plugging in electrical components.
We put together a resistor, an LED, and the power supply on the breadboard and tried to get the brightest we could get our LEDs without burning them out.
In the end we were supposed to fill out an inventory sheet on our vex robotics parts for our robot that will be built soon, but I did not have enough time to finish all the way there.
This is my finished breadboard system with a proper capacitor and working LED bulb.
