Jargon buster
Plain-language definitions for the technical terms used above.
- Grove
- Grove is a standardised 4-pin plug-in connector system for sensors and modules that avoids soldering and jumper wires, with different cable types carrying I2C, UART, analogue or digital signals. When a product is Grove-compatible it can be quicker to connect supported modules, provided the connector type, signal and voltage all match.
- 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.
- ISP
- In electronics, ISP usually means In-System Programming, a way to load firmware onto a microcontroller while it stays on the board (often via an ICSP header), or an Image Signal Processor, hardware that turns raw camera sensor data into usable images and offloads the main CPU. The surrounding context shows which meaning applies.
- 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.
- 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.
