Hello guys, I wish all of you have a nice new year!
I want to make an IR illuminator with 20 IR 940nm leds for a nightvision camera. They support 1,4V and 100mA while lighting continously. But I'm sooo confused! What battery I need? How many resistors? Is it better to connect them in series or in parallel? Thank you and sorry for my noob questions!
*Important! The leds must be (exactly) at these positions because I have create a breadboard with this circuit. The battery, resistors etc can be placed anywhere.
