This is the first Arduino course. The objective is to learn basic knowledge about Arduino and make the first simple Arduino project, which is to make a LED blink.
1. Connect the circuit
On the breadboard, the holes in column « + » and « – » are connected vertically, while the holes in column from « a » to « j » are connected horizontally. The longer pin of LED should be connected with plus(« + ») and the shorter pin should be connected with minus(« -« ). In this case, I also connect pin 13 to « + » and « GND » to « -« .
2. Plug Arduino to computer and create the code
The first time using Arduino, I should first check if the version of Arduino and the port are right.
Ok, now create the code as what’s shown in the following picture.
After programming, Verify->Upload. Then I saw the LED started blinking.
