at the moment i have no code for the effect. But exactly these chasing LEDs I want to realise. I am not the big programmer.
But there is no real need for heavy multiple effects at the same time. As I said the blinkin of the navlight
I will put into an ATTiny85-20 to avoid as much delay() as possible. So a simple routine with a for() loop should do the trick.
I will organize the LEDs in an array() and then simply will in the for() loop go through the array() to the firing LED lighting 2 or maybe 3 adjacent LEDs in every loop.
At last the flickering for the firing LED ist realized controlling the LED voltage with a PWM controlled logic level Mosfet. Maybe i try to slowly increase the brightness of the chasing LEDs this way too. Depends on how this looks.
This idea came into my mind just now. So joining here seems to be worth it! ;-)
The MEGA 2560 PRO Embed I'm using has 54 digital pins and 16 analog pins. And it has a nice little footprint of 38x55mm. So at the moment there is not need for shift registers.
I really know LED strips. I build my own Ambilight for my flatscreen. So I know what they can. This is not my problem. From this point of view they absolutely would be the better choice.
My decision came more from the model maker side. The strips are not really bendable in the needed direction to get the curve of the phaser bank. So I would have to cut them off and rewire them.
Second point is the size. I want to build the model as clean as possible. A 0402 LED has the size of a salt grain and is nearly invisible. With the strip LEDs I have the problem to get the light from
the inner side to the outside of the phaser bank. And I think a fibre will never be that bright the pure LED can be.
p.s. When I have some code I will post it here.
