Getting the RGB LED to respond like I wanted was more difficult than I thought it would be. My original idea was to have this project be a interactive example on how our country ignore the science of climate change using the light sensor and water sensor. As I put everything together it all worked, but it didn't work the way I was hoping so I had to table the idea for another time. I believe my main issue was with the light sensor, but I didn't have the time to redo what I have put together.
The result of all of this is an LED light that can be manipulated in three different ways: light sensor, potentiometer, and water sensor. The potentiometer can also be used to activate the active buzzer after crossing a certain threshold.
Materials:
- 17 Jumper Wires
- 1 Arduino UNO
- 1 RGB LED
- 3 220ohm resistors
- 1 photoresistor
- 1 Water Sensor
- 1 Potentiometer
- 1 active buzzer
