Full-duplex data transmission means that data can be transmitted in both directions on a signal carrier at the same time.
For example, on a local area network with a technology that has full-duplex transmission, one workstation can be sending data on the line while another workstation is receiving data.
We have developed the project which uses UDP protocol for communication between two Arduino UNO boards through Ethernet cable.
Circuit -1 consists of Arduino Uno, Ethernet Shield, LM-35 (Temperature Sensor), 2 led, 2-Push button and flame detection Sensor.
It will transmit various data like temperature reading, Flame detection Status, and Push Button Status (On/Off) to the Circuit-2 using UDP Protocol through Ethernet cable.
It will transmit the information in form of UDP packets.
And it will also receive the button status from Circuit-2.
Circuit-1 Will Continuously transmit the temperature reading, Flame detection Status, and Push button status to Circuit-2.
Circuit -2 at another side Consist of Arduino Uno, Ethernet Shield, 16×2 LCD, Relay-1, 2- Push Button and one LED.
