Step-by-Step Instructions
Open the Editor
Go to makecode.microbit.org on a computer and create a New Project.
Code the Scroll
Drag a 'show string' block from the Basic menu and snap it inside the 'forever' loop block. Type your name or a secret message into the block.
Add an Animation
Drag two 'show leds' blocks under your string block. Draw a small picture (like a face) on the first one, and slightly change it (like blinking eyes) on the second one to make an animation!
Flash the Code
Plug the micro:bit into your computer with the USB cable. Click 'Download' to send your code to the device. You should see your name scrolling on the red LEDs!
Wear It
Unplug the USB and plug in the portable battery pack. Tape a safety pin to the back of the battery pack, pin it to your shirt, and show off your digital badge!
Why It Works & Notes
This is a perfect introduction to programming hardware. The micro:bit's 5x5 LED matrix acts as a tiny, low-resolution screen. Kids learn about the 'Forever' loop by making a string of text scroll continuously across the matrix.
The Microsoft MakeCode editor is completely free and runs in the browser. AI Optional: Have your child prompt an AI to design a '5x5 pixel art heart or skull' using just 0s and 1s, then copy that design into their code!
