LilyPad Arduino 328 Main Board

Jargon buster

Plain-language definitions for the technical terms used above.

Bootloader

Small starter software on a microcontroller that lets new code be uploaded before the main program runs. Knowing how to enter bootloader mode matters when you need to program the board or recover it after a faulty sketch.

conductive thread

Thread made with metal or other conductive fibres so it can carry electricity while being sewn into fabric. It matters for wearable and textile projects because it can replace wire, but it has more resistance than normal hookup wire.

e-textiles

Electronic textiles are fabrics or clothing that include electrical parts such as conductive thread, sensors, LEDs, or small controllers. This matters because parts for e-textiles need to survive bending, sewing, and sometimes washing.

IDE

Short for Integrated Development Environment, a program used to write, run and manage code. It matters because some learners prefer a traditional coding workspace instead of a guided notebook-style lesson.

microcontroller

A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.

PCB

A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
