Arduino Serial Begin: Multiple Serial Ports For Arduino boards with more than one serial port the HardwareSerial class will define numbered Serial objects; For a single Serial port (Arduino Uno/Nano) you write: Serial.begin(115200); For multiple Serial ports you write ...
Multi Serial Mega: Use two of the serial ports available on the Arduino Mega. Physical Pixel: Turn a LED on and off by sending data to your Arduino from Processing or Max/MSP. Read ASCII String: Parse a comma-separated string of integers to fade an LED. Serial Call Response: Send mult...
The Leonardo and many 32-bit boards (such as the Arduino Zero, Adafruit Metro M0, and SparkFun RedBoard Turbo) have a second hardware serial port in addition to USB serial. The Teensy 3 board from PJRC has three serial ports in addition to USB serial. The Teensy 4.0 board has seven se...

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. ...
Each machine will have a different combination of serial ports, depending on what other devices you have used with your computer. On Windows, they will be listed as numbered COM entries. If there is only one entry, select it. If there are multiple entries, your board will probably be the...
When working withESP32 WiFi/Bluetooth MCUunderArduino SDK for ESP32, you will notice thatSerialwork just fine. ButSerial1andSerial2do not.ESP32has 3hardware serial portsthat can be mapped to almost any pin. But,Serial1andSerial2will not work. In case of ESP32 this just has to be done...
