Let's teach the kids to code in a fun way, and see it in action with the pixel art drawing from Microsoft Excel.
Microsoft Excel, a Microsoft Office application that, in general, having boxes on the computer screen when we open it. Whereas, pixel art drawing, is often described as a “sandbox drawing”, using building blocks, as we see from the love shape drawing. We see the similarity in both. That's the idea when I having my breakfast at McDonald one of the morning.
With the similarity, Microsoft Excel seems a perfect tool, to extract kids' attention to draw the Minecraft art, by learning up the code.

Microsoft Excel is using VBA (Visual Basic Application), a programming platform, that can interact with row and column, text (value) and color from within.
Like any programming tool, we need an editor for the purpose. For Microsoft Excel, the editor is called “Microsoft Visual Basic for Applications”. The editor came with Microsoft Excel, no separate download is required.
Well done! We are just prepared the environment for our Minecraft art drawing. As we notice, we need the row and column in a square, in order to draw the character in Minecraft way.

To learn to code, we need to know what is variable. Variable is nothing but a container that we use to keep the thing like string, number or object. Variable can change its form from time to time. For example, before we start our coding, we may initiate a variable with 0 value. But then we add this variable with 5, so, the value of the variable now becomes 5 (0+5). Variable become very useful when we involve with many calculations, or use it to represent something that meaningful.
Let's switch back to our VBA editor by pressing "Alt+F11" on the keyboard. In “HelloWorld_Click” module, within the “Sub” and “End Sub”, let's remove the 2 lines for the rows and columns and replace with below lines of code:
We notice there is a different way to assign a number or string or an object. For number and string, it's easier - just assign the variable with an equal sign. Whereas for object, we have to use "Set" in front of the variable.

Tips: We notice there is a single quote “ ’ ” at line 13. What the single quote meaning is really nothing but to put a comment on what our code is doing, so that we know it for future, or understand the code easily when the code becomes longer like thousands of lines. For the VBA (Visual Basic Application) programming language, whenever there is a single quote is found at the beginning of the line, the line will not be executed.
“For… Next” loop is used when we want to carry out the same actions repeatedly. We know most of the pixel art drawing contains only a few colors, and when we put it on sandbox or row and column in Excel, we know it is repeating almost the same colors for each row. Thus, "For... Next" loop is a perfect command we need.
The first "For... Next" loop we called it as outer loop, and the second "For... Next" loop inside the "For... Next" loop we called it an inner loop. And what's inside the "For... Next" is the action, which is the repeated task we want to tell Microsoft Excel to do. To explain it further, assume we have x number of tasks to carry out repeatedly, and inside this x number of tasks, we also have y number of tasks.

Data is the thing that we want to keep it somewhere for later use. Data can be the variable value that we assigned previously, but data stored in "variable" will not retain when we restart Microsoft Excel (application). Database is the place to keep the data, where it will retain after the Microsoft Excel (application) is restarted. In our example, the rows and columns from Microsoft Excel are our database structure.
Surprise to see what we just draw? Although just 2 lines (line 4 & 5), we notice the top part of the heart shape now.
Let's review our code, by referring to the pictures. Please take note that the numbers on the pictures represent the steps in the below bullet lists:

But wait! Our pixel art heart is halfway completed? That's right! We need to finish it all. Let's continue to enter the drawing point or data to the table/database, by referring to the heart picture. After we completed the data entry, click on the "Draw Me!" button to check on the change. If the heart is not properly drawn, most properly the drawing point is not entering correctly. Correct it and "Draw Me!" again.Editor's note: The brush sets linked below are not necessarily the brushes that were used in this tutorial. The brushes below were recommended by the author. Please feel free to use brushes from your own collections.
Usually I'm not much of a sketcher, so coloring is usually my first step, but when I'm painting something more detailed, I like to think about what I am doing. It is important not to get attached to the sketch, most of the times the final piece is different from the initial sketch, use the sketch to help you with the overall composition. If you feel more comfortable using a pencil and paper, draw it by hand and scan it into your computer.
Ok, so after you have an idea of what you want to paint it's time to select you color palette, this is not an easy task. What I do is select the base color depending on what I am painting, and start mixing colors you think would fit your purpose. Since I'm painting a lot of rocks and grass, my base colors are grey and green. In this step it's important if you start thinking about the light. As you can see in the picture below, the light is coming from the right side, so I just started to paint with lighter colors on the spots facing that direction. One thing that could help you with the light and color selection is the sky, when you have the base color for the sky that can make you work much easier, so I just added a sky to help me to create more realistic colors, lightning and mood.

So as you can see, now I have a rough painting and I can now start to add details. The next thing to do is quite simple, take your lasso tool and start defining the mountains so you can have more accurate results when painting them.
After that just cover all the selected area with a base color, in my case I just used grey. When I want a more detailed piece, I use clipping masks, because I can easily control my painting area. It's quite simple to do it, just create a new layer above the one that you want to detail, and then go to Layer > Create Clipping Mask (or just press Alt + Command/Ctrl + G) now, everything you paint on this layer will only be visible on the area of the layer from below. On this new layer, start by defining the light and shadows; try to make it simple so you have a better overview on your light.
When working on the mountains, keep in mind that the veining on the mountains is actually quite easy to achieve. Use a small round brush, set to color dodge with blood red, and then start to paint, as you experienced before using color dodge, every time you repeat a brush stroke on the makes the color brighter.

So, now it's time to start the detailing process. To help me with that task I have some nice brushes that I have collected over the years. I have included some brush sets in the Tutorial Assets section of this tutorial. Feel free to give those brushes a try. The biggest piece of advice that I can offer is to get to know the brushes that you use. Then you will know which brushes are best for your situation. Once you know the capabilities of the brushes you are using for the project, you can start to add in some details. Occasionally, I will use a texture brush when I paint but for the most part, I use simple brushes like the one below to paint in details.
The clouds can be a bit tricky, and again, depends on the level of detail you want, in this case I used a simple cloud brush to get the main shape.
To detail the clouds I used the smudge tool, it gives you good control over the details on that kind of material. Select the smudge tool, with a the same brush used before around 5-6px large, and check the finger painting box, this mean that if you use the smudge tool on the canvas you can paint a small stroke before you actually start to smudge. However there is a nice shortcut for this feature that I
