Arduino and Computer Connection

Arduino and Computer Connection

This article will explain the connection between the Arduino board and computer. What can I do and how it works?

Connection between Arduino board and computer What can do?

- Upload firmware by Arduino IDE.

- Receive/Send data between Arduino boards and computers.

Principle of operation (Uno, Mega2560, Pro Micro, etc.)

        Principles of connection between Arduino boards and computers. For example The firmware was uploaded to the Arduino board. The data from the computer was transferred to the USB To Serial converter, which converted the voltage from the computer to a TTL level and sent it to the MCU. Micro Controller Unit) via the Rx-Tx pin. The Arduino board has an updated firmware. The Arduino board and the computer are the same as uploading the firmware.

Notice

- Comport of Arduino Boards are Fixed.

- If the Arduino board is attached to the computer, it will lose Hardware Serial.

But in case of some boards such as Leonardo, Pro mini, Due, and other boards. The connection between the board and the computer will not use USB To Serial external because the internal MCU has a USB To Serial BUILTIN already.

Notice
- Comport of Arduino Board ate switch between Hardware Serial and Programming Port.- Do not lose the hardware Serial like the first.
