I would like to built myself a LED PAR light ficture of the “flat” type based on the Arduino platform (using an Atmegaxxx in SMD if possible), for example like this:
It is a very simple design, just a switching power supply, some LEDs, a control PCB with a µC and a enclosure.
These things are very expencive though and just for fun I would like to built one or thwo myself, regardless of the final cost.
There is just one problem: These things use microcontrollers and a display (four 7 segment display and four function butons) to select different modes (DMX, automatic, sound to light…) and values to control the LEDs.
And I am a complete noob regarding microcontroller programming. The best thing I can do is blink a few LEDs and drive a dot matrix display :-[
Now my question: Did anyone ever built or duplicated such a LED fixture? Maybe someone can share the source code that was used?
I searched the web for such projects, but the only thing I could find was either just dimming the three RGB colours via dmx or some random dmx tutorials, I really want nearly all the functions like the device in the link.
Another idea would be to buy only the control- PCB of a cheap chinese product, like this:
And either try to read the code off of the microcontroller (it`s probably secured anyways…) or just transfer the parts to my own custom made pcb.
The homemade version would have some pluses for me, I could customize the menu to my own needs and the price would be cheaper than a bought one.
Thanks and greetings.
