Room lighting project

Components used

• Arduino Uno
• Jumper wires
• MOSFET
• Strip of 4-pin RGB LEDs (SMD5050)
• Rechargeable Battery (9V)

About the program

The sourcecode is in the directory Project_adv.

1. Compile and upload the sketch to the Arduino.
2. Open the Serial Monitor.
3. Send a 4 character code consisting of characters between '0' and '9'.
   The first 3 characters specify the intensity of the R-G-B colours and the last character is for mode.
   • 0 - off,
   • 1 - constant colour,
   • 2 - bloom to bright,
   • 3 - rainbow scroll (RGB),
   • 4 - rainbow scroll (natural),
   • 5 - blink in succession (Disco night).

Help! The Arduino is receiving characters I did not send

Turn off Line Endings (CR LF / LF / CR) in the Serial Monitor before sending.

Demonstration

The directory Videos contains videos recorded during a project run.

Simulation and schematic

View on TinkerCAD.
Note: The simulation varies slightly from the IRL product due to a difference in the availablity of components.
