1/07/15

Used multimeter to measure voltage coming from wall plug.
Then, used multimeter to measure voltage from different batteries.


We then used the multimeter to measure the resistance of a few resistors and compared it to the known values.






Made circuits using LEDs and different resistors

Built a square bot

Circuit board with resistors soldered on
Our first task was to solder on some resistors on the board.
Soldered wires
Next, I cut off the end of an AC/DC adapter and solder on some other wires to the positive and negative ends of the adapter. I then used shrink wrap to prevent the wires from touching.
Bread board with LED and 100 ohm  resistor
Using the AC/DC adapter from before, I used it to power an LED on a bread board. However, a resistor must also be used in order to prevent the LED from blowing out.
Bread board with LED and 470 ohm resistor   
I then used a 470 ohm resistor in the circuit and observed that it light up less dimly.
