Hi sudeep,

You can communicate two arduino’s using different communication protocols like UART, SPI, I2c.

using UART you can connect RX,TX pins to other arduino and write the code like Serial.print(for writing to other arduino) and Serial.read(for reading the data from other arduino).
you would be finding sample codes in arduino.cc for communication.
