Hey, I have (2) 5mm Yellow LED's*3VDC*20mA*55mcd
also, (2) green LED's T-1 3/4 PD75mW
and I'd like to know what kind of resistors I should get for them cause, I have
(5) 22k OHM resistors 1/4 watt (5% tolerance)
I don't think they'll work so can someone just tell me what kind of resistors to get
for each single LED, I don't want a link to the resistor calculator, it confuses me, can someone just post or PM me which ones to use for optimum brightness?

Get 120 ohm, 1/4 watt. 22,000 ohm is waay to much and won't work.

get one of those for each LED, or for all of them because I want resistor for each LED not all of them in a series
