Jargon buster
Plain-language definitions for the technical terms used above.
- common-anode
- A wiring style for multi-colour LEDs where the positive side is shared and each colour channel is controlled on the negative side. This matters because common-anode and common-cathode LED strips are not interchangeable without a suitable driver.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
