Here is a screenshot of one the first examples in MicroCode: smiley buttons.

The goal of this program is to show a smiley and plays a happy sound when pressing A, and a frowney animation and unhappy sound when B is pressed.

The MicroCode language, is defined in terms of pages, where a page has a list of rules, and each rule consists of a When section and a Do section, each with a list of programming tiles. For this example, we have 4 rules.

The first rule tells MicroCode to show an image when 'A' is pressed on the micro:bit.

You will find more samples in the MicroCode documentation.

• when press button A, do show image smiley.

The next rule tells MicroCode to play a sound when 'A' is pressed as well. All rules run at the same time.

• when press button A, do play sound emoji happy.

The next two rules are similar but for button 'B'.
