I have a 12V powered LED circuit. 6LEDs in total, with 50ohms resistors.
Now, I would like to make these LED flash, at a slow rate (1/4 second on, 1/4 second off). I am a bit familiar with the 555 timer circuits, but will the 555 be strong enough to drive those 6LEDs (they are 20mA, 2V leds). What if i increase the LEDs to 24 LEDs in the future (4 strips of 6 LEDs), will the 555 still be enough, or do I need to add a relay or something similar?
Will it be better to go with a micro-controller? I am not familiar with that, but would like to try it just for fun. Where will it be a good place to start with micro-controller circuit driving LEDs (there are tons of sites, I know, but would like to start somewhere good and complete). Micro-controller is probably overkill for this, but this would be a good time for me to learn it.
Thanks
