I’m working on a Halloween project and wanted to run it by you wonderful people before I get started.
I want to power 20+ LED diodes that will be placed in pairs to look like red glowing eyes throughout my yard. I am writing a program that will randomly make the lights go out and turn back on immediately to look as if the eyes are blinking. The LEDs I ordered have a resistor hard wired and they say the diodes are “12V” whatever that means. They didn’t specify the ohm rating though.
My power supply I am using is 12V for landscape wiring. I was planning on using a regulator to change it to 5V to run the arduino. I wanted to know if the Arduino can handle using all of the digital pins to power these LEDs.
