How to interface Arduino UART

UART Interfacing

Serial communication allows sending and receiving data or commands between the computer and control board. In this project, we will be sending a character from the Computer and it will be serially printed on the serial monitor.

Also, here a character string will be given to the computer and that will be displayed on the serial monitor.

                                                                                                Figure1: UART Interfacing

Step1: Procure Components Required

• USB Cable
• Computer with Arduino software
• MEP_ROBO UNO with Atmega IC

Step2:  Write the program in Arduino UNO IDE

During Serial Transmission: mepits.com will be displayed on the serial monitor.

During Serial Reception: a character given from the computer will be displayed on the Serial Monitor.

Step3: Connect the USB cable to the board and PC.

Step5: Download the program to the board.

Step6: Check the Output.
