Our system will be driving 12V led strips directly from this power line. You should not use a transformer significantly different than 12V. The circuit is show below as a [https://fritzing.org/home/ fritzing] breadboard diagram. You can also download an easier to read [[Media:TV_Mood_Lamp_fritzing.pdf|pdf]] or the original [[Media:TV_Mood_Lamp_fritzing.fzz|fritzing file]].

You will want to use solid-core wire for the point-to-point connections on the board. These will hold their position, and fit easily through the holes in the protoboard. To connect to the screw terminals, use the stranded wire. It is much more flexible and will greatly reduce the risk that you break a wire when inserting or removing the system.

==== Inputs ====
The circuit system is rather straightforward. The input power jack connects from the center terminal (power) to one end of the power switch. The other end of the power switch connects to the VIN of the Arduino system. The ground of the power jack must be connected to the GND of the Arduino system. The potentiometers should have their "low-side" tied together and then connected to the Arduino GND. They should also have their "high-side" tied together and then connected to the Arduino 5V regulated power. The wiper of each potentiometer should then be connected to A0 and A1 respectively. If hooked up "correctly," when the potentiometer is all the way "on," the wiper should be connected to the "high" side. Now, what constitutes "on" is left up to you. If these are hooked up incorrectly, then the wiper can be inverted in software as a simple fix.

==== Outputs ====
The rest of the system serves to drive the LED lights. These lights will be connected to a 4-pin terminal in the center of your board. This terminal has power (white or black wire) and then wires for green, red, and blue signals. The power comes directly from the VIN pin ('''not''' the 5V pin). Each of the green, red, and blue signals is connected to a "low-side" MOSFET switch. The source of the MOSFET's are connected to GND, the drain is connected to the appropriate pin on the 4-pin header, and the gates are connected to pins 3 (green), 10 (red), and 11 (blue).
