Basic 16x2 Character LCD - RGB Backlight 5V

Jargon buster

Plain-language definitions for the technical terms used above.

LCD

LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.

LED

A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.

parallel interface

A parallel interface sends several bits of data at the same time using multiple wires. It can be faster than simple serial connections, but it uses more microcontroller pins, so it is less convenient for small projects with limited wiring space.

RGB

Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
