Hi, i would imagine this will be simple for most of the people on this forum. I made an LED panel containing 40 LED's and powering it using a transformer from an old garden light set.
On another forum (not specifically for electronics) I have been given masses of differing advice ranging from "the LED's will blow as soon as you plug it in" to Some will light up brighter than others" and finally "that is a terrible circuit - you need 1 resistor per LED".
Now, just quickly, the LED panel I made has been on for 6 hours and every LED is bright, evenly lit and has not burned out)
Rather than show you what I have done so far, can someone spec me a circuit - simple drawings will do to make the following design.
I have 4 transformers at my disposal so if you could tell me which is best to use, that'd be great!
I want to use white LED's
