How do you have the Arduinos connected? How would you do this if the second device was a PC?
Asking how to do serial communications, when there is a perfectly well documented class for doing serial communications, is rather pathetic.
Besides the usual serial protocol (which can be emulated in software on any pins) there are several ways, probably I2C (aka TWI) or SPI could suit you:
