Story

RGB LED Control using Touch Pad

In this project, I am going to demonstrate how to control the on board Intelligent RGB LED using Touch pad with the help of the idIoTware shield.

Working

The Touch pad on the idIoTware shield acts as the input, so every time you touch it, the color of the RGB LED will keep changing. You can use it to make a mood lamp that can change its color, and be controlled by using the touch pad.

Configuring idIoTware Shield

Step 1/2: Jumper connected to CLR pin and D6 for RGB led
Step 1/2: Jumper connected to CLR pin and D6 for RGB led
Step 2/2: Connect the “BUZ” pin to the center pin on SEL 1, 3 pin header. This will connect buzzer to arduino pin A1
Step 2/2: Connect the “BUZ” pin to the center pin on SEL 1, 3 pin header. This will connect buzzer to arduino pin A1

Once we upload the code in Arduino, you can change any color of RGB LED on the shield. You can have your own RGB lamp with 16 million colors on the tip of your finger, without hassling a lot with wires and a breadboard.

Wasn’t it amazing?! Now design your own lamp for a final personalized touch. With the idIoTware shield the sky is the limit.

Code

/*

  The IdIoTWare Shield uses Touchpad attached to pin 4.
  
  The IdIoTWare Shield uses a addressable  RGB LED to display a spectrum of colors.
  The CGShield library abstracts the details and provides 
  you the following function:
  
    color(RED, GREEN, BLUE);   // three arguments are the pixel color, expressed as red, 
                               // green and blue brightness levels, 
                               // where 0 is dimmest (off) and 255 is maximum brightness (0-255).
                               // for example to set RED color, color(255,0,0);
  
  In this example, WS2812 Led changes its color as we toch the touchpad.
