Jargon buster
Plain-language definitions for the technical terms used above.
- Grove
- Grove is a plug-in connector ecosystem for sensors and modules that avoids soldering and jumper wires. Grove compatibility matters because it can make it quicker to add supported I2C devices, as long as the cable and voltage are suitable.
- 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
- An image signal processor is hardware that helps process raw camera data into usable images or video. It matters for vision projects because it can improve camera handling and reduce the processing load on the main CPU.
- 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.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
