I am sort of migrating towards the Arduino from the Basic Stamp, and I am curious, is there any built-in way to address I/O pins in groups? In other words, if I had four LEDs on pins 0-3 and I wanted to copy a BCD variable to those four pins, would I have to use digitalWrite(pin, value) four times,…

Access I/O pins as word, byte, nibble?

Thanks and 73 Jason! I searched PORTD on the Aurduino site and was able to find out how to manipulate the I/O that way.
