Varying The Voltage On A Dio?

Skip to comments Jump to end

Is it possible to vary the voltage output by one of the digital ports? I have a laser I want to use that works best at 3.3V - more than that and the laser gets dimmer. Any suggestions (other than tying resistors in line)? I can use resistors if I have to but wondered if there was a more practical and elegant way.

Thanks,

Bret

My Error, I look at all three pins as the port - and not just the communication pin. Sorry for my confusion.
