Perform the pocket cut 1/8" deep. This requires the initial pocket cut over the entire region, followed by an inside cut to clean up the pocket cut. The system automatically stays slightly off of the line during the pocket cut as the edge is not as clean when large amounts of wood are being removed. Hence, the inside cut to clean.

You will want to offset the cut slightly (1/16"? - need to verify again) to make the insertion of the faceplate easier.

The electronics are all about controlling the red, green, and blue intensities on an RGB LED strip - likely in some sort of fade pattern. Our specific RGB Led strip lights are rated at 12V, therefore, we will use a 12V transformer as an input. We will use an [https://www.arduino.cc/ Arduino] microcontroller. Specifically, the stalwart [https://store.arduino.cc/usa/arduino-uno-rev3 | Arduino UNO Rev3].  We need to add three power transistors to the Arduino to be able to deliver adequate power to the red, green, and blue LEDs of the led strip. Therefore, we will use the [https://www.adafruit.com/product/196 | Proto-Screw Shield] from [https://www.adafruit.com/ | Adafruit].

Our system will be driving 12V led strips directly from the  power transformer input. You should not use a transformer significantly different than 12V. The circuit is show below as a [https://fritzing.org/home/ fritzing] breadboard diagram (click it to enlarge). 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]].

The Input wires connect the external components to the screw terminals. 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.

The output system serves to drive the LED lights and consists of the internal wires on the shield. 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).
