I have several high power LEDs controlled by Arduino Nano. These LEDs are powered by a dedicated 12V/3A regulated power supply. The Arduino itself is powered separately via the mini-USB from regulated 5V power supply and it controls the LEDs via TIP122 transistors. So far so good. Now 2 power supp…
