Learn about Serial communication between Arduino. Transmit data between two Arduino using RX/TX lines. 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. Delphi and Arduino Arduino is a single-board microcontroller. This example uses 5 LEDs that will be controlled from the Delphi program via serial communication. I want to read a string from my Arduino via Usb(Serial). Delphi-xe7 arduino tpapro ApdComPort read. Serial communication Python to Arduino.
DescriptionArduino Serial Print
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), and some have several.
On Uno, Nano, Mini, and Mega, pins 0 and 1 are used for communication with the computer. Connecting anything to these pins can interfere with that communication, including causing failed uploads to the board.
What Is Serial Communication
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() .
Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board). Don’t connect these pins directly to an RS232 serial port; they operate at +/- 12V and can damage your Arduino board.
Arduino Multiple Serial Communication
To use these extra serial ports 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.
