Starting the process of building all the electrical connections.

Screw down terminals being used to group ground and power of outputs together.
Common signal wires left individually.

Example of procedure explained above.

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.

Saul Payan - FPD - Data Sheet# 1

                           DATA SHEET 

                                            Presented here is the Data Sheet (graph) of the:
          LED Circuit Board, located in the back of the car dashboard of the First Person Driver(FPD).
The goal of this Data sheet is to leave the reader feeling confident in their ability to distinguish between the 17 different LED output wires and their purpose, know all the inputs located in First Person Driver itself, and have a general idea of how the electronics system works.

       In graph #1, we explain which LED "D" Number (Ex. D-14, D-7, D-15) connects to what pins on the board, along with;

 ~  Wire Color Scheme ( first-most color being the "main", with a single-stripe secondary color) 
  ~  LED-Color Output

  * There are 20 Male-pins present on-board, only *15 are used as outputs (15 LED's on-board).
 Of which, 15 wires (  D-1 through D-15) stem from the Female connector, connecting to the Male pins (1 through 20) on-board. D-19- and D-20 are used as Ground and Power. Each of the wires, D-1 through D-15, can act as a ground, creating a closed circuit, when connected to D-20.

  Subsequently, there will be 2 additional graphs, that;
~ assign a function to each of the 15 LED Outputs.
~ show the 10 (different) Inputs I will be using, and how each of them turns on one specific                  LED Output, 
    along with the 4 Unused LED outputs I plan to change the function of.
   (Note- Number of outputs may change in the future. Some inputs have multiple outputs, along with no outputs at all,which will be shown in graph #3).

We will also explain how we plan to use the Speedometer and Tachometer as additional (Non-LED) outputs (12 Outputs).

*(Directly underneath, I have provided a diagram of reference, so the reader can acknowledge the       1-20 pins (located on the Circuit board) being discussed).

The speedometer and Tachometer are additional outputs displayed on the car dashboard. They will receive a signal from an Arduino,which will transmit input from the potentiometer located on the Gas and Break pedals. When powered, we will measure the resistance of the potentiometers and see the difference when they are and aren't fully pressed down. This will allow us to come up with a ratio of MPH that can be sent as a signal to the Tachometer and Speedometer.

Mr. Burnham - Driving the Tachometer - How to turn on and off 12 with 5 volt Arduino or Raspberry Pi IO

Saul, this link may be a way to drive the tachometer and Speed gauges.  You want to protect the 5 volt Arduino / Pi system, but be able to have a 12 volt current switch on and off... see this link

• https://www.baldengineer.com/pwm-3-pin-pc-fan-arduino.html
• https://electronics.stackexchange.com/questions/230802/12-volt-switched-by-5-volt

It's for PWM control of a 12 volt fan.  We could maybe also use a standard motor controller like https://sites.google.com/view/steam-clowns-closet/motor-controller-l298n-dual-h-bridge-motor-controller

Today for open lab I worked on the First person driver. I was able to screw the seat back down,but a screw is missing. We are going to try and see if we can acquire the full set of screws.The day before today, I soldered and connected the chair cables to the platform. Also,I was able to measure the resistance of both the gas and break pedals. The data is logged into my notebook. I plan to upload it soon. The potentiometer on the gas pedal seems to be broken so I plan to restore it or replace it.

My goal is to have a fully functional First Person Driver. It is a Remote control drone that reacts to your actions on the the Driver's seat. The user will be able to view the location of the car based on the camera view,which will be mounted on the car.

There are many things that we must do before the FPD is fully functional,of which include;
-measuring the resistance of every sensor we plan to use and labeling the wires.
-Fixing the broken end of the turn signal on the steering wheel
-Connecting all the sensors onto a breadboard controlled by an arduino or raspberry pi.
-programming code for each sensor.
-Adding a monitor that can receive transmission from the drone style car.
-Adding sensors and a  volt meter to the car. measuring how fast the car goes and converting it into a ratio of MPH.        -Here are a few photos documenting the slow but steady process.-
