I want to create runway lights for a project. I want to have 2 columns of 4 LEDs. I'd like 1 and 2 on at the same time and then 3 and 4 and so on until it repeats with 1 and 2. Can I use a 555 timer for this? Ideally I'd like to have the sequence flash quickly, but would also like to be able to adjust the frequency to slow down if need be.
Also, I want to use high brightness LED's which would have a combined drop of 28.8 Volts. Any recommendation of a small battery or other power source would be helpful. If not I guess I'll wire 4 9 volts in series.
Here is the layout of the LED's:
8 7
6 5
4 3
2 1
Any and all help is appreciated. Thank you.
