Hi guys, I've decided to change the layout of my current system, this involves moving a Pololu micro serial servo controller to a software serial port, the controller can be operated by a logic-level serial input. My question is what is the output voltage of a digital pin configured as a software serial pin (i.e. does it exceed 5V)? Cheers.
It won’t exceed the supply voltage (you didn’t say what board you’re using)
Hi AWOL, sorry forgot to mention I'm using a Duemilanove board I have a 9V supply to Vin.
The 9V is regulated down to 5V for the processor, so a digital HIGH won't exceed 5V
Got it, I guess I'll just go ahead and do the connections then. Cheers.
