Hello,
Iam still pretty new to electronics this is my first time using a RGB led i plan on each color to be on at one time no mixing colors, the part iam using is a common Anode RGB I planned on using a 5v power source to connect my anode to, the max led ma each color can handle is 20ma which i plan on using only 18ma per color.I'm using a online led current limiter calculator to calculate the ohms i need for each led color resistor but the calculators are giving me ohm values that would put my led around 30ma.Iam using a schematic i made in flastad to see how much current i would be drawing which came out to around 30ma using the falstad simulator.Im not sure were iam going wrong or were to look?Would falstad be given me bad results?There is a link to my schematic just a simple led with resistor.Any help is appreciated thanks
