The breaking of the bread(board)

Today we had the breaking in of the breadboards:
behold the glory of 3 Light emitting diodes wired in parallel.

The green one is emitting a small amount of light because it has 2 large resistors regulating is current, (approximately 10400 ohms) the middle LED has a 100 ohm resistor and the top LED is wired to a 1000 ohm resistor. As you can see, the greater the resistance, the less light emitted from the diode.

Today we were introduced to the wonders of the multimeter. We used it to check for continuity in our soldered circuits from day one, we used it to make sure that our 5 volt power supplies were not going to explode when we put them into the wall, and we used it to check voltage and resistance in a circuit built on a breadboard.

Resistors are color coded to display their resistance, and each color represents a decimal value or a power of 10.
The following image explains how this works:
Finally, we were assigned our vex robotics kits today, which we will be using to create a square bot and to build the final project.

Tune in tomorrow, same bat time, same bat channel!
