ASSIGNMENT

Connect 3 LEDs (red, green, and blue) and resistors to the Arduino breadboard and create a custom way to control the brightness of each LED using serial input from the keyboard.

In addition, create a unique diffuser for your light.

MATERIALS USED

3 LEDs (red, green, blue), 3 220 ohm resistors, Halloween Ghost Decoration

ARDUINO CODE

Included images of three color LEDS blinking and one single light with diffuser. Need to finish the diffuser assignment with 3 lights.

Description:

Initially, I tried making diffusers using glass, aluminum foil, toilet paper tubes, etc. 

I've settled instead on using a disposable soup bowl to contain the light, the cut-off bottom of a plastic container, and cotton to diffuse the light within the bowl. 

My program uses a prompt that allows users to type in their favorite type of fruit from a given list.  The LEDs then light up in the color of that fruit. 

Materials for diffuser:

8 oz. soup bowl

My diffuser is made of a ping pong ball, with a bit of filling to even out the light. 

Code for the stepper is below: It's not 100% perfect, but it does the job ! :) 

Description

Use the r, g or b key to increase the light level with 20%
