Learn about input and output, and use them in your color mixing.

What is coding?

What is coding?

Humans use coding to tell computers what to do. Based on a computer program, we'll carry out any task.


Learn how you can send us instructions, and write a program to build animals.

What is binary?

What is binary?

Computers use the binary number system to store all your information with only two symbols, 0 and 1.

Learn how to count like a computer, and write your name using zeros and ones.

What is an algorithm?

What is an algorithm?

Before you write any code, you need a plan for it, also known as an algorithm.

Brainstorming ideas for it is always worth it because with a simple plan, following the steps will be no brainer! 

Learn how algorithms are part of your daily life and start designing your own.

What is a computer bug?

What is a computer bug?

With humans writing Megas of lines of code every day, it's easy to make mistakes. Becoming a good detective is key to spot them and write programs that make what you want. Learn how to search for coding mistakes and get your code clean.

What is a repository?

What is a repository?

Coding requires a lot of trial and error. Many times, you'll find yourself moving forward with a program thinking you're going in the right direction only to realize hours later that it wasn't such a good idea after all. That's when you wish you could go back on time! Well, humans have an easy way to do just that —they use repositories.

What are bits and bytes?

What are bits and bytes?

In The Binary World, we live with millions of other bits and bytes. In this blog post, you'll learn what bits and bytes are, how to write the alphabet in bits and bytes, and a brief history.

What is RGB?

What is RGB?

A computer has its own way of working with color. It's called RGB, which stands for red, green and blue. Learn what RGB is, how to write colors in RGB and a brief history about it.
