I used to build circuits when I was young but life changes and I got into computers and Photoshop as a career.
I've been watching and reading tutorials on the basics to try and catch up. However I've come across a puzzle that I can't solve. I have a high power LED from a solar flood light and am trying to determine the amount of resistance needed. It was powered with 3 1.2v @2000mah nimh batteries
I'm thinking the pc board had a resistor going to the LED but it was fried along with my brain from old age! TIA
