The LED mood light should now be adding a soothing ambient glow to the room. Now, make the project unique. There are many things that can be done to tweak the mood light. Here are a few things to try:
- Edit the code.
Change the values of the delay or color starting values, or re-write the transition() function to fade the LEDs differently.
- Re-wire the circuit.
Swap out LED colors for a different color variety, or add a variable resistor to the circuit to adjust brightness.
- Stylize the cover.
Draw on the paper cover or use a different material to add extra effects.
- Combine with other projects.
Try syncing the colors with music.
Hopefully this project inspires further experimentation. The Arduino board is incredibly versatile and accessible to hobbyists of all backgrounds. This is just one of many simple projects which can be constructed using this technology. Keep tinkering!
