The following is a detailed voltage map of the Color LED lamps available in the Lab. This table was used to find the proper DAC chip used to control the colors remotely. The location of the color coding in the table corresponds with color position on the remote. R(Red), O(orange), Y(Yellow), G(Green), Lb(Light Blue), T(Teal). B(Blue), Pu(Purple), P(Pink), W(white). Combinations of these letters refer to the mixed colors.
VOLTAGE MAPPING:
The LED lamp is backwards polarized. To directly inject voltage into the LED and produce assorted colors, connect the positive lead of the power supply directly to the mount of the LED array that has the (+) symbol. Connect the negative lead to the dismounted wires before the RGB resistors. The power supply has two channels which can be used to apply multiple voltages. Using a bread board and external resistors can give you more than just two voltages to get an even broader arrange of colors. This same process can be used to measure the voltages at any location. Connect the negative lead to the location of interest and leave the positive lead connected to the + on the led using an alligator clip or a hook.

Each lamp comes with 120V circuit that is used to accommodate for any use. It can be replaced with a 12V wall charger. This method was used to test the circuitry and fill in the table above.
COMPONENTS IN THE CIRCUIT:
- 3 resistors: Red(R), Green(G), Blue(B)
- 2 capacitors
- Positive lead (Pink wire), ground (white wire)
- IR sensor (black wire with black sensor at the end)
- 2 Digital Analog Converters(DAC), "24c02c 877541347"
The LED array has three columns of three LEDs. Each column correlates to its corresponding colored wires and RGB resistors. The first column of LEDs are all red; second are all green; third all blue. When being used to produce any color, each column of 3 LEDs is turned on simultaneously depending on which combination of RGB is needed. When disassembling these lamps, be sure not to dismount the LED array because the system runs hot and it will burn out if the correct amount of thermal paste, white in color and underneath the LED array, is not present. To remove the LED array, unscrew the two screws holding it down but have thermal paste present to reapply if turning the LED on.
These LED lamps are controller via IR (Infrared). It has three cables controlling the IR dongle: positive 5v(red), ground (black), data signal (White). To analyze the signal given to the IR dongle from the remote, splice a wire into the white cable. Keep the white cable connected to the system so it still receives a signal but can also send the information to the Logic Analyzer. After doing this, start the Logic Analyzer software, Saleae, and then plug in the LED to an outlet. Start the sampling on the software and press keys methodically to see the information relay on the software. This information can be reproduced by an arduino using an appropriate sketch.
Infrared sensors are controlled by a signal given by the remote control. These codes come in the form of serial codes that are later decoded by the internal circuit to do whatever the remote demands. To acquire these codes, an arduino, arduino sketch, and the IR sensor from the LED were used in combination with the steps from http://www.instructables.com/id/The-Easiest-Way-to-Use-Any-IR-Remote-with-Ardiuno/?ALLSTEPS. These codes will later be used to an array of LED flood lamps.

The infrared approach was not successful and is not recommended. We chose to bypass this system and use three MCP4902 DACs to control each RGB resistor individually. Refer to the MCP4902 DAC page for connections to arduino and relevant information.
CONNECTIONS TO ARDUINO, MCP4902 DAC, TRANSISTORS;
Need more than 5.5V from DAC so need to figure out transistor connections, power supply issue.
