3 dni temu · Use two of the serial ports available on the Arduino Mega. Sometimes, one serial port just isn't enough! When trying to communicate with multiple serial enabled devices, while also sending info back to the main serial window, a few extra RX/TX ports can be a welcomed thing.
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.

21 kwi 2013 · Dzisiaj chciałbym przedstawić Wam pokrótce, co to jest i jak można wykorzystać port szeregowy, i jego monitor w zastosowaniach z Arduino. W tym wpisie wyświetlimy na panelu LCD tekst wpisywany poprzez serial monitor.
8 lis 2024 · 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).
8 lis 2024 · 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.
You'll need to select the entry in the Tools > Board menu that corresponds to your Arduino board. You have a Mega2560, therefore it has an ATmega2560 microcontroller, selected by default as processor. Select the serial device of the board from the Tools | Serial Port menu.
