Used for communication between the Arduino board and a computer or other devices. All Arduino boards have at least one serial port (also known as a UART or USART): Serial. It communicates on digital pins 0 (RX) and 1 (TX) as well as with the computer via USB.

Thus, if you use these functions, you cannot also use pins 0 and 1 for digital input or output. You can use the Arduino environment’s built-in serial monitor to communicate with an Arduino board. Click the serial monitor button in the toolbar and select the same baud rate used in the call to begin(). The Arduino Mega has three additional serial ports: Serial1 on pins 19 (RX) and 18 (TX), Serial2 on pins 17 (RX) and 16 (TX), Serial3 on pins 15 (RX) and 14 (TX).
To use these pins to communicate with your personal computer, you will need an additional USB-to-serial adaptor, as they are not connected to the Mega’s USB-to-serial adaptor. To use them to communicate with an external TTL serial device, connect the TX pin to your device’s RX pin, the RX to your device’s TX pin, and the ground of your Mega to your device’s ground.
Serial Communication Ppt
The Delphi application I wrote to test the PC-to-Arduino communication is very simple. Six checkboxes are used to turn an Arduino digital pin HIGH or LOW.
Circuit for Serial communication between two Arduino Boards Step 2: Code for Sender Arduino This is code for Sender Arduino Board. First, initialized a string with data 'Hello'. In setup, the Serial Monitor is begun at 9600 Baud.
Serial Communication Arduino
In loop, sent the data to receiver Arduino using Serial.write. For more information about Serial.write, Step 3: Code for Receiver Arduino This is code for Receiver Arduino Board.
First, initialized a blank string to store serially received data. In setup, the Serial Monitor is begun at 9600 Baud. In loop, received the data from sender Arduino using Serial.readBytes. For more information about serial.read, Step 4: Upload the code to Arduino Upload the code to the sender and receiver Arduino Board. Make a circuit as per the given diagram after uploading code. Hello will be transmitted from Sender Arduino to Receiver Arduino. You can transmit your data or variable like this.
