The goal of this project is to have a good set of programs to run the RGB light strip. The strip is used for the Moleigh dome but could also be used for the 24inch telescope.
Observations in the dome:
- The "Darkest" setting is still quite bright
- We need a better box and more sturdy electronics
- It would be good to have a way to point the strip towards the wall so we only see reflected light
Analysis with the code:
- It's difficult to get brightness=1 or 2 by hand. When you move the joystick from black to brighter it immediately jumps to a higher value (like 4 or 6).
- Idea: We could have smaller steps in brightness if the brightness value is below 30.
- Idea: For values below 3 for any value, we could switch the PWM on and off for each loop.
- Looking at the PWM on the oscilloscope it seems the Arduino is doing what it needs to do (but a better oscilloscope is needed)
RGB light strip has amplifiers for arduino to be able to drive the RGB light strip.
Example program below uses the Joystick to change color.
