Welcome to the Spoken Tutorial on Blink of LED using Electroblocks. |
| Slide 2
Learning Objectives |
In this tutorial, we will learn about:
|
| Slide 3
System requirement |
To record this tutorial, I am using:
A working internet connection to use ElectroBlocks. |
| Slide 4
Prerequisite |
To follow this tutorial, learner should have a basic knowledge of
|
| Type | Let us open the ElectroBlocks website using Chrome browser. |
| Show the electroblocks default blocks
Point to right side electroblocks circuit diagram |
ElectroBlocks home page displays default blocks for Blink of an LED experiment.
On the right side, a circuit diagram is auto-generated for the Blink of an LED. |
| Point to LED
Point to simulation area. |
In this setup, an LED is connected to an Arduino board.
By the end of the experiment, you will see an LED blinking at a specific time interval. |
| Zoom the breadboard and point to the rails.
Highlight the cursor area Point to row in breadboard Point to breadboard Point to vertical column of 5 holes Point to circuit |
Let us understand the circuit connection.
The two rails at the top and bottom of the breadboard are called power rails. The red rail represents the positive connection and the blue rail is the negative connection. Each row is connected horizontally. Positive and GND connections between Arduino and breadboard are already set. Each vertical column of 5 holes is internally connected. These rails are called terminal rails. The LED is connected to Arduino pin 13 through a resistor. The LED's other leg is connected to GND. |
| Highlight Blocks
Point to default generated blocks Point to block inside loop block. Point to Turn LED ON block Point to Turn LED OFF block Point to both Wait for 0.2-second block |
Let us see the default blocks generated to blink an LED.
The loop block contains four blocks: two LED blocks and two wait blocks. The first LED block sets pin 13 to ON, turning the LED on. The second LED block sets pin 13 to OFF, turning the LED off. Each LED block is followed by a 0.2-second wait block, creating a delay. This means the LED will stay ON for 0.2 seconds, then turns OFF for 0.2 seconds. |
| Click on the code icon
Highlight the comment section |
On the top tool bar, click on the Code icon to view the automatically generated Arduino code.
The code includes self-explanatory comments for better understanding. |
| Click on the home icon and click the play button
Point to simulation area |
On the top toolbar, click on the Home icon.
Let us click the play button in the simulation area to simulate the circuit. Observe the LED is turning ON and OFF with a 0.2 seconds delay. |
| Change the pin number in the LED block
Change the LED# in both LED blocks to 10 Point to simulation area. |
Now let's modify some parameters in the blocks.
Change the LED# in both LED blocks to 10 from the drop down box. This connects the LED to pin 10 of the Arduino in the circuit. Observe the updates in the circuit diagram as we make changes in the blocks. |
| Update both wait blocks to a 1-second delay.
Click on the Code icon Point to updated code |
Let us update both the wait blocks to a 1-second delay.
Click on the Code icon to view the updated code. You will see that the LED pin has changed to 10. The delay is set to 1 second. |
| Click on the Home icon.
Click the Play button Point to simulation area |
Click on the Home icon.
In the simulation area, click on the Play button to start the simulation. Observe the LED blinking with an updated delay of 1 second. |
| Point to step by step controls.
Click the Previous Step button Click the Next Step button Point to yellow outline block in working area Point to status window and loop changes in simulation area |
To view the simulation step by step, use the step controls.
Click the Previous Step button to go back to the start of Step 1. Click the Next Step button to move forward through each block. The currently running block will be highlighted with a yellow outline. Watch the simulation steps in the simulation area and loop progress in the block area. |
| Click on the Download icon and select the download project.
Cursor on xml file. |
Let us see how to save the project.
Click on the Download icon on the top toolbar and select the download project. It will download the Blink of LED project as an xml file in the Downloads folder of your computer. |
| Open the xml file.
On the top toolbar, click on New file /Blank file icon and press ok. Click on the Projects icon and click on choose file. Choose the .xml file and click on OK. Point the cursor on all the blocks and code. |
Let us open the saved xml file.
On the top toolbar, click on New file /Blank file icon, and press ok to create a blank file. Click on the Projects icon on the toolbar and click on choose file. Choose the .xml file that you have downloaded and open the project, click on OK. You can see all the blocks and code that was generated. |
