Fermion: TCS3430 Tristimulus Color Sensor (Breakout)

Jargon buster

Plain-language definitions for the technical terms used above.

breakout

A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.

dynamic range

Dynamic range describes how wide a span of values a sensor can measure, from very low to very high. For a light sensor, a wide dynamic range means it can work in dim indoor settings as well as bright sunlight without changing hardware.

I2C address

An I2C address is the number a device uses so a microcontroller can tell it apart from other devices on the same I2C bus. It matters because two devices with the same fixed address may conflict if used together.

integration time

Integration time is how long the sensor collects light for each measurement. Longer times can improve readings in dim light, while shorter times can respond faster or avoid saturation in bright light.

LED

A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.

programmable gain

An adjustable amplification setting inside the ADC that makes small input signals larger before they are measured. It matters because choosing the right gain helps use more of the ADC’s range without overloading the input.
