FAQ:

Q: What is pin mode in Arduino?

A: “pinMode” is a function developed by Arduino to configure the GPIO or digital pin of the Arduino on-board microcontroller. “ pinMode ” is a function developed by Arduino to configure the GPIO or digital pin of the Arduino on-board microcontroller. Microcontroller pins, like the ones on the Arduino can work as either INPUT or OUTPUT pins.

Q: How to use TX RX pins in Arduino?

A: Use SoftwareSerial (just check the internet you’ll understand) to communicate with module if you have to use Serial monitor for your arduino in PC. These are serial (bit-by-bit) communication ports. Connect TX to another RX pin on another device, RX to TX.

Q: Can you use an Arduino analog pin as an output?

A: Of course. In fact in generally for AVR microcontrollers, it is easier to use the pins as digital than analog. In old days before Arduino, to use the pins as analog pins, there were several configuration involved. So Arduino made it easy by defining the pins that are connected to ADC as analog pins. I have used Arduino analog pins as output in several projects. In case of Arduino UNO, A0 pin will be 14 A1 will be 15 and so on.

Q: How to use analogread function in Arduino with examples?

A: How to use analogRead in Arduino. The analogRead is a command mainly used to program the analog pins on the board. If you are using analogRead functions, it indicates you are making the pins as input i.e. you can connect the Arduino analog pins with any sensor and read its value by making the analog pins as input.
