Introduction

This 'module' allows you to add sounds and control an RGB Led to your 3D Printer or any other project based on Arduino board.

It's called module but it's a complete Arduino project because it uses an Arduino as microcontroller.

The Sound part and the Led part are independents.

It's controlled by Marlin firmware. Acts simulating to be an BlinkM and uses M150 Gcode.

The Led part is based on Micah Riddell design of Amblone: http://fritzing.org/projects/uln2003a-amblone-v2/

Hardware

Hardware needed:

Arduino Board

The core of the module can be any Arduino board. We need SDA/SCL comunication, 4 digital I/O and 3 PWM pins. All working at 5v.

(Not an Arduino board working at 3.3v)

Sound module (WTV020-SD-16P)

For the sound, the modules control an WTV020-SD-16P (easy to find in Ebay & cheap).

Loud Speaker

8Ω Speaker is conected to the WTV020 to play sounds.

ULN2003A

Used to pass PWM output to RGB Led.

Resistors (1/4W)

1 470Ω 1/4W (Busy Led)

2 4.7KΩ 1/4W (SDA,SCL lines)

3 1.5KΩ 1/4W (Voltage divider) (*) R1

3 2.2KΩ 1/4W (Voltage divider) (*) R2

3 1KΩ 1/4W (Voltage divider) (*) R2

(*) This resistors are used as a voltage divider to down the 5v output of Arduino I/O pins to 3.4v in my case (1.5k to pin, 3.2k (2.2k+1k in series) to Ground).

You can use 1.8K to pin and 3.3K to ground to simplify, and you will obtain 3.24v . You will need 3 of each.

RGB Led Strip

12v RGB LED strip, common positive, that can be manually controlled.

Others

Female/Male pins, protoboard, cables, solder ... to create an Arduino Shield containing the Hardware.
