Time Narration
00:01 Welcome to the Spoken Tutorial on First Arduino Program.
00:06 In this tutorial, we will learn how to:

write an Arduino program,

Compile and upload the program and Blink an LED.

00:19 Here, I am using:

Arduino UNO Board,

00:23 Ubuntu Linux 14.04 operating system and

Arduino IDE.

00:30 To follow this tutorial, you should have: basic knowledge of Electronics,
00:36 basic knowledge of writing a C or C++ program,
00:41 and, Arduino UNO Board with USB power cable.
00:46 Let us open the Arduino IDE to write our first program.
00:52 Here, we can see various menus in the Menu bar.
00:57 In Arduino environment, each program is saved as Sketch.
01:03 By default, it creates the name as Sketch underscore and a name.
01:11 You can change the name by clicking on File and then on Save.
01:18 Type the filename as BlinkLed.

Now click on the Save button.

01:26 This is the default program environment with two empty functions -void setup and void loop.
01:35 Now, we will write an Arduino program to blink the LED.
01:41 I have placed my IDE and the Arduino board side by side.
01:47 This will help us to see the execution of the program and the output in the board.
01:54 For this LED program, I want to blink pin number 13.
02:00 It is a digital input/output pin connected to this LED internally.
02:07 Notice the highlight with the marker.
02:10 Now, we have to write our code.
02:13 void setup function stands for setting up a microcontroller.
02:18 In our case, pin number 13 has to be set up first.
02:24 To do this, we will use an in-built function called pinMode.
02:31 It has two parameters - pin number comma mode.
02:36 So, type: pinMode open brackets 13 comma output close brackets semicolon.
02:48 Why should we keep the mode as output?
02:51 This is because the pin number 13 is internally connected to the LED.
02:58 It will glow when the voltage is high but it will not glow when the voltage is zero.
03:05 We have to configure mode as ‘output’ to serve voltage to the LED.
03:12 Next we will write code to the void loop function.
03:17 Before we blink a LED, let us glow a LED.
03:22 There is a function called digitalWrite which will write to a digital pin.
03:29 This function has two parameters as pin number and value or state.
03:36 Already, we know the pin number as 13. The value should be HIGH or LOW.
03:44 So, type: digitalWrite open brackets 13 comma HIGH close brackets semicolon.
03:55 We want to glow the LED. So, the voltage should be HIGH.
04:00 That's all. The code is very simple.
04:04 Next step is to compile the program.
04:08 Click on the Tick icon on the menu bar to verify the program.
04:14 This will compile our program into binary format which is understandable by the microcontroller.
04:22 You can see the compilation status at the bottom of the IDE.
04:27 Next we need to upload the program to the microcontroller.
04:32 Click on Right arrow button on the menu bar to upload.

Alternately, you can select Sketch menu and then upload.

04:48 You can see the TX RX blinks for a while. This indicates the transmission is ON.
04:57 Now you can see the LED is glowing.
05:01 How to turn off the LED?

We have to modify this program such that the second parameter value is LOW.

05:11 Now, let us compile and upload this program.
05:16 You can see the LED is off now.
05:20 We know how to turn ON and OFF the LED.
05:25 Next, we will modify the program to make the LED to blink,
05:31 that is, ON and OFF, with one second interval.
05:36 We will change the program as shown. Delay is a built-in function which pauses the program for certain amount of time.
05:46 I will type: delay open brackets 500 close brackets semicolon.

Here, 500 means 500 milliseconds, that is, half a second of delay.

06:01 Next, type as digitalWrite open brackets 13 comma LOW close brackets semicolon.
06:12 This makes the digital pin 13 to OFF mode.
06:17 How long we want to turn it OFF?

Type: delay open brackets 500 close brackets semicolon.

06:28 Again, we want to OFF it for 500 milliseconds.
06:34 Let me explain the Void loop program line by line again.
06:40 Void loop is an infinite loop and it will execute continuously.
06:45 The pin number 13 connected to the LED will be in HIGH state for 500 milliseconds. And then, in the LOW state for 500 milliseconds.
06:57 This program is executed repeatedly in the loop.
07:02 Let us upload the program.
07:05 We can see our LED is blinking.
07:10 This brings us to the end of this tutorial. Let us summarize.
07:16 In this tutorial, we learnt about: how to write an Arduino program,
07:21 Compile and upload the program and blink an LED.
07:27 Do the following assignment. Change the delay timing to 1500 in the above Blink LED program.
07:37 Compile and upload the program and observe the blinking in the LED.
07:45 The video at the following link summarizes the Spoken Tutorial project.

Please download and watch it.

07:53 The Spoken Tutorial Project team conducts workshops using spoken tutorials and gives certificates on passing online tests.

For more details, please write to us.

08:06 Do you have questions in THIS Spoken Tutorial? Please visit this site.
08:13 Choose the minute and second where you have the question.

Explain your question briefly. Someone from our team will answer them.

08:24 Spoken Tutorial project is funded by NMEICT, MHRD, Government of India.

More information on this mission is available at this link.

08:35 This tutorial has been contributed by FOSSEE and Spoken Tutorial Project, IIT Bombay.
