HI,

I need your help for making LED board which is based on simple Connection no scrolling..
so, please give idea how to do this using 12V supply voltage of 800mA.
LED range from 60-80's...

Thanks

 

3 LEDs can be connected in series, and a resistor added to this in series again. Such chains can be paralleled and connected to the 12V supply. The resistor is for current limiting, and is decided with the LED forward voltage and the 12V supply limits.
