Could
somebody from the UK please post a link to the exact Green LED's they use and the Resistors as well please. Cheers guys
Go to eBay and find a shop by user Bright Components. You can get the yellow, green and red LEDs all with same voltage drop.
just email them and tell them you want 3mm LEDs all with the same voltage drop. You can just tell them how many you need and can buy them outside of eBay.
Ok. I just checked my old email when I last bought.
I got the 3mm diffused LEDs from bright components.
These LEDs all have a voltage drop of 2v and current of 20mah (directly what I've been told by bright components)
Using the 9v power source, and putting this info into the led series online calculator,
I got these resistors.
56 ohm 1/4 watts resistors
Just get these and you should be ok. I have the exact same ones.
Like I said before, some LEDs from different sellers will have different voltage drops and current mah.
The ones I've mentioned work for me along with those resistors.
Ive also used the same LEDs for a few 3v setups, I've just used different resistors.
Let me know how you get on!
