I could use some opinions on how best to accomplish the following in terms of Arduino hardware (or any other option).
5 momentary buttons
1 varying control voltage (such as a pressure sensor)
1 sonar-based distance sensor
8 separate groups of RGB LEDs to control (Pulse Width)
1 group of red LEDs (controlling on-off and dimming)
1 output to a sound playback card to trigger any of several recordings
I am assuming it’s best to get a daughter board capable of handling 8 PW outputs. it’s important to understand that each of the 8 groups of RGB LED’s might be displaying different colors at the same time, and there could be as many as 5 LEDs in a group.
I’ve done a basic graphic to give you a visual of what it looks like in my head, I will put it in my next post.
If there’s a way to do this with one card, or if someone can suggest what daughter board to use, etc, that would be great.
