Description
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.
Serial 2 0 10 0 115200. Set dynnotchwidthpercent = 0 set dynnotchq = 250. It should eventually start going down and should go very low or to zero. The package provides the installation files for FTDI USB Serial Port Driver version 2.12.16.0. If the driver is already installed on your system, updating (overwrite-installing) may fix various issues, add new functions, or just upgrade to the available version. And so forth for 3 more serial dilution steps (giving 1/8,000, 1/16,000, and 1/32,000). You end up with 1.0 ml of each dilution. If that is enough to perform all of your tests, this dilution plan will work. If you need larger volumes, increase the volumes you use to make your dilutions (e.g. 2.0 ml + 2.0 ml in each step).

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.

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

.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.
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.
