There is no resistor built into this high intensity blue LED. On the package it says 5V is typical and 6V is max. How can I increase the voltage to use 6V when I only have a 5V pin? Also, the previous question remains unanswered. Do I need a resistor in circuit which isn't calling for it?
We really need to see a link to your specific led to see what you are working with as it is certainly not just a simple standalone blue LED if it requires a simple 5-6vdc connection.
