I want to control a RGB LED strip with one potentiometer and a button to change what I am controlling.
As you probably guess, I am pretty new to Arduino and I do not know how to program this.
So, if you did not understand the short-version of my project, here is a more detailed version of it:
Only one potentiometer, and one button to cycle the things I want to change.
The things I plan to do is: Change red color, green color, blue color, brightness.
I use a Arduino mega 2560 at the moment, but I am going to change it to an Arduino nano when that arrives. The led strip is a WS2812B, the library I use is FastLED and type NEOPIXEL.
I don't know anything about the LED stuff, but you could start experimenting with the button push control and pot logic just using a button, and a pot connected to the Arduino, and monitor what your code is doing via the serial monitor.
I would look at the example sketches that come with the IDE, then I would practice with one colour and the pot to dim using PWM.
Next I would set up a counter to count button presses with each number = a colour (1 is red 2 is blue 3 is green 4 is all off etc) however you want the button presses to work.
Then I would set up variables for each colour and write some code that says if count = x then pot value goes to x colour variable.
There are ways to make the button count reset to a "home" position after a preset amount of no activity if required.
Please read the first post in any forum entitled how to use this forum. http://forum.arduino.cc/index.php/topic,148850.0.html .
Then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
