Jargon buster
Plain-language definitions for the technical terms used above.
- LDR
- A light-dependent resistor is a component whose resistance changes with light level. It is useful for simple brightness sensing, and an ADC board is needed to turn its changing analogue voltage into numbers a microcontroller or computer can read.
