Week 3 Learning About Electricity : IE How to burn up LEDS and melt a breadboard

This week we learned about Voltage and how to measure the voltage of the components on the breadboard. Here I am measuring the voltage, make sure and remember red to red and black to black, just like when you're jumping a car battery! Here's Gordie checking out his 12 volt power supply

Next we made a basic LED circuit by adding a switch and some LEDs into the mix. Here's my HOT LED circuit

Then Gordie really made it hot by almost blowing up an LED, check out his smoking breadboard! Sadly Gordie did permanently disfigure himself using the 12 Volt power supply for too long so we switched it to a lower 9 Volt supply

Next we turned the lights up and down with the Potentiometer.
As you turn the potentiometer from one end to the other, measure the voltage at the center position. The pot is acting as a voltage divider, dividing the 5V into two parts. As the voltage feeding the LED goes up or down, the LED gets brighter or dimmer. No code here, just great videos.
