Hi,
I want to build an alternating LED flasher that uses 2 sets of 48 blue LEDs that operates at 3.2VDC to 3.8VDC and the current is 20ma. This will be in a car. So it has the 14V. I was thinking of using a 555 and a 4017 but can the 555 handle the current? Each one will generate a 20ms pulse at a frequency of about 0.5Hz.
