I designed this PCB for my high school's robotics team. It is an RGB LED light sign that have 3 channels of color for each letter. The letters can flash, fade, stay on, and go in crazy mode. The effects of the animation can be changed with the rotary encoder. The cost is approximately 30usd if you build 10.

Step 1: Gerber Available Here

Step 2: It Is Useful As a Growth Lamp

/* fade w/o pwm

Fades an LED that is not connected to a PWM pin This was modified from the Blink without Delay code The circuit: LED attached from pin 13 to ground. Note: on most Arduinos, there is already an LED on the board that's attached to pin 13, so no hardware is needed for this example. *

/ constants won't change. Used here to set pin numbers: const int b1 = 5; // the number of the LED pin const int g1 = 4; const int r1 = 6;

const int b2 = 7; // the number of the LED pin const int g2 = 8; const int r2 = 9;

const int b3 = 10; // the number of the LED pin const int g3 = 11; const int r3 = 12;
