How To Make Code For Arduino IDE Software And How To Upload It To Arduino Board?

In the previous two chapters we saw the arduino ide software tool and the arduino uno board. Now it is time to combine between them, meaning write some simple sketch, upload it to the board and see some result. My arduino is connected right now using a usb able to my computer and i am using the arduino ide.

Let’s write some lines of code, and please don’t worry if you don’t understand them 100%. As we are going to cover that much more deeply in the next section. What i would like us to do is to write a program that will turn the led l on for 1 second. And then off for 3 second, very simple

Now if you already have the hardware equipment than please try that by yourself, as in later stage we will build much more complicated system. The good news is that we can find in the examples such almost similar sketch

Just go to “file” menu, “examples”, “basics” and select “blink”. And let me bring that to the screen, now we are getting some sketch being developed by the arduino community. First few lines are comments or remarks used to describe the goal of that sketch in high level going below. We have the "setup" function where we set pin 13 as output for accessing the relevant led.

Now the main program body is inside the loop function. First line write constant 5v signal to pin 13 and then wait for 1 second. Then send again to the same pin 0v and wait again for 1 second. Now we would like to change that to 3 seconds now before uploading the software, i will click on "verify" to verify that everthing is ok

Now, i didn't get any error message, it is being done and i can now doing the "upload". Now we can click on “upload”, now during the uploading time of the code, we will see that the tx and rx leds are blinking. For a shot period, let's do that clicking on upload you see very fast the the tx and rx were blinking, as soon as this finished the arduino micro-controller will start running our program forever looking on the board, we can see the l led blinking on and off based on the delay time in our program.

We just passed the first milestone and now we know how to upload a program to the Arduino that is actually doing something, still we need better understanding about the programming syntax so we will be able to develop much more complicated sketches. And this is something we will cover in the next section.
