Saul Payan - FPD - LED Circuit Lab

Here is a lab I performed to test and see if any of the LED's were burned out.
I found that all the LED's were working properly.
In the next photo, you can see all the LED's turned on. This was a very simple test, meaning the LED's turned on based on an open/closed circuit. I plan to individually blink the LED's soon and come up with an algorithm. I could have also potentially have set a singular LED blink code and connected power to one of the Digital pins on the Arduino.

The materials needed for this lab were;

• The LED circuit board (with 20 pins, 15 LED's) 
• Female connector (with 17 wires: 1+,1-)
• 2 Alligator Clips
• Screw Down Terminal
• Arduino Uno (no code needed, optional LED blink code)
• 7 Male-Male wires
• Power source (5 volt or USB cable)

Procedure 
Connect all the wires leading from the circuit board, onto a screw down terminal (D-1 through D-15). Divide the wires into 4 terminals.

• Leave wire D-20 (power) as an individual terminal
• Screw  down one Male-Male wire on of each of the five terminals
• Connect all of the 4 Male-Male wires to one Alligator clip. The 4 wires should share ground with all 15 of the "D"wires. Once this is done, connect the open side of the Alligator clip to a Male-Male wire, and place the wire on the ground of the Arduino.
• Do the same for the other side of the terminal for D-20, but instead place the wire on 5V,or if you plan to use an LED blink code, use one of the numbered pins.
• If it is a closes circuit, all the LED's should be on.

I took this photo (showing the ground,power,and common connections a linear potentiometer) to able to tell exactly where each wire is connected, as well as for documentary purposes.
We have learned, through tests with a potentiometer, that the resistance of the Gas pedal potentiometer  (Input) is not at 10k ohms,the desired amount. This shows that the potentiometer is not working properly.
In the next photo, you can see that I took of the Potentiometer, which we plan to replace soon.
