Problem: Am I powering these LEDS best way as I can?
What Im making: Two sided red strobe light using an ATmega328P chip from an Arduino uno and basic blink code.
I have looked in to so many how to videos but never could find a clear answer when it comes to powering more than one string of LEDs with a constant current driver. I like to know am I doing it right or is there something better I could do to power these leds and make them blink with the Arduino without killing it.
The LEDs are them cheap 1w Ebay ones (red 2.2v 350mA)
Power supply is a lead acid 12v 5AH
Using an Arduino to blink the LEDs (at no point the LEDS will be on longer than 2 seconds)
R2,R4 are found by 0.5/LED current
