In this tutorial we are going to create our first arduino project. It will be a simple blinking light-emitting diode.
To install Arduino IDE on your Linux Mint system you should: 1. In the terminal type and install Arduino IDE
sudo apt-get install arduino
2. Add your user to the dialout group
sudo usermod -aG dialout %username%
where %username% is your username 3. Reboot your computer 4. Plug in your Arduino board. Open Arduino IDE and click Tools -> Serial Ports -> /dev/ttyACMx. There you should see the port number your Arduino board connencted. 5. Go to File -> Examples -> 01.Basics -> AnalogReadSerial and try to upload a project to your board. Everything should be ok.
For our project we need: 1x Arduino Uno 1x Breadboard 1x LED 5mm 1x 220 Ohm resistor 2x wires
Arduino project schematic:
Sketch:
//this function executes only 1 time when you initialize a program
void setup()
{
//setup pin №13 in the output mode(voltage source)
pinMode(13, OUTPUT);
}
void loop()
{
//apply high signal on the pin №13(5V)
//current will run through the LED and it will start to shine
digitalWrite(13, HIGH);
//delay microcontroller in this state for 100ms
delay(100);
//apply low signal on the pin №13(0V)
//light will go out
digitalWrite(13, LOW);
//delay microcontroller in this state for 900ms
delay(900);
//once you upload a sketch function loop starts working repeatedly
//LED starts blinking one time per second
}
Result:
