Connect the anode (+) of the LED to pin 3 of the Arduino board. Connect the cathode (-) of the LED to ground (GND) of the Arduino board. Upload the code to the Arduino board. 4 .The LED should start ...

The “void setup()” section only runs one time, at setup, when it sets the pin with an LED connected to it (pin 13) as an output, meaning the pin controls the light instead of receiving input ...

void setup() is a function that is used to set the pins to be used as INPUT or OUTPUT. Baud Rate is also set in this function. Baud rate is the speed by which the microcontroller board communicates ...

When you launch the Arduino IDE for the first time or when you create a new sketch from the ‘File’ –> ‘New’ menu (Ctrl+N), the editor opens a new sketch template containing skeletons for the functions ...

In arduino uno, a LED will be already designed at the pin13, ... // The setup function runs when you press reset or power the board void setup() { // initialize digital pin 0 as an output. pinMode(0, ...

Some Arduino boards, Arduino Uno for example, only has one serial port, but we can still read data from TFmini while do not disturb the data transmission from Arduino's TX to PC. It only need to ...
