Hi everybody,
First of all I apologize if I posted in the wrong place.
Secondly, I would greatly appreciate it if anyone could send me in the direction of books or the like to help me with my education in these sorts of things, starting from the super basics and going up to fairly advanced topics.
Okay down to the meat of where I need some assistance. My little project has become more than I anticipated. I am looking to create flickering candle flames from 3 LEDs for a theatrical production. They would need to be fairly bright as they need to appear real from approximately 100' away all the way down to 15' away. I was experimenting with Arduino and with its hardware PWM outputs I was able to drive each LED to make it appear as one flame that had the appropriate movement. From there I am currently exploring how to make them controllable over the DMX lighting protocol or over 0-10v analog control, both which are currently above my level of understanding.
For a small number of flames I would have no problem controlling them this way, however I need to create 100 separate flames in groups of 12 on 8 separate units. This means that I would have to purchase a minimum of 8 arduinos (but more likely 16 since I would want many of the LEDs to be flickering at different rates).
Therefore, I am reaching out to the experts of this community to ask for lots of advice for what to do here, even if your advice is to send me to someone capable of designing the circuit I am willing to do that.
All in all I would like the circuit to do the following.

All in all I would like the circuit to do the following.
- Create a flame of 3 LEDs flickering at different rates to emulate a real candle flame.
- be able to be "dimmed" in one way or another
- Control the dimming by either DMX or 0-10v analog control.
- Be able to address the unit if DMX control is used.
- Be powered from a 120v 20amp AC circuit
