4. Write and Decode Secret Messages in Binary

Binary code is like a secret language that computers use to talk to each other. It uses only two symbols, 0 and 1, to represent all letters, numbers, and other symbols. For example, the word “HELLO” in binary code looks like this: 01001000 01000101 01001100 01001100 01001111.

1. Learn more about How Computers work using binary code.

This video from Code.org explains how computers use binary code to represent numbers, words, images, and sounds. It breaks down the basics of binary and data representation, making it clear how everything in a computer is ultimately processed as a series of 1s and 0s.

2. Create your own secret messages in binary code

Use the Alphabet to Binary Converter below to write and code your own secret messages. Just type your message in the “Enter text” box and click “Convert” to code it. You can copy your secret message and write it on the board for your class to decode or share it with a friend.
