Just playing around with a R3 Uno and some LEDs, creating the shine of fire.....
Some troubles with the camara (whitebalans) but we where happy with the results
Hi, thanks for reaction. The Flashrate is random, the effect on the video is much more then in "real life", in real it loks more natural.
And a lot for work? No, not really, it is simple to build. At this time it will turn on when it gets power, but in the futere i will program a LDR and a scene. Then a steady light will turn on when de power is connected and the lights in the room are dimmed. Then, after a while, the fire is lightened up.
Nice effect! My question would be to ask why you used three LED's for this? I did something similar in the past with a single LED, and for my firelight effect I set minimum and maximum values and a random delay between changing brightness values, plus added in the occasional flicker. I might have to rebuild that circuit again to see how it compares to what you're getting with multiple LEDs.
The idea behind the 3 LEDs was to create a "full" fire, but maybe it can be done with 1 or 2. I was teaching my 10 year old son how he can program multiple LED sketches and after that I was programming the fire with the same board, so thats why 3 LEDs are used
It would be nice to see your fire-effect with one LED, waiting for it:thumbsup:
Well I found the original code, it was written up as part of a DCC accessory decoder on a Nano when I was playing with a PCA9685 board (16 PWM outputs from an I2C bus). I also had an effect for an arc welder which always seems to be popular at the shows. I'll see if I can clean this up to use on another board I already have running.
