200mcd or 800mcd White LED's
« on: July 29, 2009, 08:09:41 AM »
What is better for Triggers and Speakers, 200mcd or 800mcd and also is a 10k Ohm ¼w Resistor okay for the LED's?

Of course you want more MCD. It doesn't necessarily means more light being given from the led but higher is better. And it can require higher resistor.

Use this calculator to find the appropriate resistor->http://www.hebeiltd.com.cn/?p=zz.led.resistor.calculator

And I have a blue 160 MCD 0603 and it gives off light pretty bright.

PS: You post to much thread  :tup:

Will a 10ohm resistor be okay?

I'm sorry I'm not an expert on resistors, you have to wait for w-gaming and blazin and the others. They helped me along this mod ^^

What are you hooking it up to?
If its a 5 volt supply use a 60ohm resistor to have 3.4 volts and 25mA going to the LED.

If its a different supply tell me and ill tell you what resistor.

I have read your personal message... i'm sorry, i'm going to connect them to a LM386 so i can use the hold switch and also is there a tutorial for how to connect a LM386 to the LED's.... thanks
