    I am making a prop and I need to have LEDs that will pulse at an adjustable rate from 100% to 50% not on and off. I am rather new to this though I have had experience soldering and putting a pre made schematic together.

    Thank you in advance for any help in pointing me in the right direction.

    That could be overkill however, put a resistor for full brightness, then insert a second resistor to dim it with a switch.

    Read Chapters 1 and 2 of the same article, they go into how LEDs work.
