101 Serial 0(RX), 1(TX) 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 seri...

soft_serial.begin(9600); And now you can use it as the hardware serial. For the list of functions you can use, please refer toSerial Reference Examples of Use Cases for SoftwareSerial: Arduino - GPS Arduino - MP3 Player Arduino - RS232 ...
tinkerers, hobbyists, makers, and beginners. You can feed an Arduino board a set of instructions for it to carry out certain tasks. It is able to read the inputs and turn them into an output, for example, it will read a finger on a button and turn on an LED. ...

Arduino Due The Arduino Due is based on a 32-bit ARM processor. It has the same amount of input/output pins as the Arduino Mega, just much more powerful. It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports...
Serial.println("Error on HTTP request"); } http.end(); //Free the resources } delay(10000); } Testing the code To test the code, simply compile it and upload it to your ESP32 board using the Arduino IDE. Then open the serial monitor and check the result. You should get an output...
