please post.

thanks very much

3.3V: 5V(supply) - 3.3V(LED drop) = 1.7V(Drop across resistor) 1.7V(Drop across resistor) / 240 ohm (Resistance) = 7.08mA (Supplied Current) The more current (up to the rated max) you give an LED the brighter it is. So the resistor allows you to tune the current and hence the brightness. Just remem...
