Lab 1 :: Light 'em up
I've learned that I'm extremely clumsy w/ the solderng iron. I kept soldering the pins together, or breaking something, or just ruining it. Once THAT was out of the way, the rest of the lab was very straight forward. We put the LEDs in series and in parallel, and we used a potentiometer to vary the voltage being fed to the LEDs.
One mistake we made is we used a larger resister than the 220 Ohm. So of course nothing was lighting up. But we would measure the voltage across the LED and we got a reading, but no light. We finallly traced it to the resistor.
Measuring voltage and amperage was simple, once you figured out how to switch b/t the two types of readings on the multimeter.
