How to use Arduino Software Serial - The Engineering Projects
By default the diagnostic output from Wi-Fi libraries is disabled when you call Serial. begin. To enable debug output again, call Serial. setDebugOutput(true). To redirect debug output to Serial1 instead, call Serial1. setDebugOutput(true). For additional details regarding diagnostics using serial ports please refer to the documentation.
Check whether Arduino is connected via Serial( USB) with
obtillaart made a that scans with different I2C speeds. If you use longer wires or libraries that use higher I2C speeds, the Multispeed I2C Scanner is very useful. (verified with UNO, 2009, MEGA) Sketch. Open a new sketch and copy the sketch below into it. Upload it to the Arduino and open the serial monitor.
ESP32 Arduino Serial over Bluetooth: Client connection
I'm trying to connect to an Arduino Mega 2560 unit connected via USB serial port in my Linux based PC. Using C code, I'm trying to send and receive simple text strings, just I'm able to …

Getting IP address of device connected to SoftAP Issue
I have been searching around the Internet to find if there is a way to check whether an Arduino is connected to a PC or not. For example: if my PC is turned on, the Arduino will listen to any serial commands it receives, BUT if my PC is turned off, the Arduino will receive some random characters.

Communicate with Your Arduino Through Android
Arduino Uno is a microcontroller board based on the ATmega328P ( datasheet ). Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the ATmega8U2 USB-to-TTL Serial chip. External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a
