Jargon buster
Plain-language definitions for the technical terms used above.
- 3.3V TTL
- 3.3V TTL means the serial logic signals use 3.3 volt levels rather than 5 volts. This matters because connecting it directly to a 5V-only signal can damage the module or cause unreliable communication unless level shifting is used.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- lux
- Lux is the standard unit for measuring how much light falls on a surface, similar to how a light meter reports brightness. A sensor that outputs lux gives readings that are easier to compare between rooms, outdoor conditions, and different projects.
- Tolerance
- Tolerance tells you how far the real resistance value may be from the printed value. A 1% resistor is useful when a circuit needs more predictable behaviour than a looser 5% or 10% part.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
- wavelength
- The distance between repeating peaks of a wave, often used to describe the colour of light in nanometres. For visible lasers and LEDs, wavelength tells you the approximate colour, such as red, green or blue.
