platform io change baud rate

To change the baud rate in C++ using PlatformIO, you will need to follow these steps:

1. Open your C++ project in PlatformIO.

2. Locate the file where the serial communication code is written. This file will typically contain the setup() function.

3. Within the setup() function, you will need to use the Serial.begin() function to initialize the serial communication. The baud rate is specified as an argument to this function. For example, to set the baud rate to 9600, you would write:

cpp Serial.begin(9600);

1. Save your changes and compile your code.

2. Upload the compiled code to your target device.

By following these steps, you will be able to change the baud rate for your serial communication in C++ using PlatformIO.
