Microsoft IoT Pack for Raspberry Pi 3 - w/ Raspberry Pi 3

Jargon buster

Plain-language definitions for the technical terms used above.

ADC

An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.

electrolytic capacitor

An electrolytic capacitor is a type of capacitor that can store relatively large amounts of electrical charge in a small package. It is commonly used for smoothing power supplies, reducing noise, and short-term energy storage, but it usually has polarity so it must be installed the correct way around.

Headers

Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.

IoT

Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.

male-to-male

A male-to-male cable has plug-style connectors on both ends rather than a socket on one end. This matters when choosing a cable because it must match the female sockets on the modules or boards you want to connect.

microSD card

A microSD card is a small removable flash memory card used to store data such as audio, images, logs or program files. Its capacity and formatting (often FAT32 or exFAT) affect how much can be stored and whether the card needs preparing before use.

photocell

A light-sensitive component whose electrical resistance changes with the amount of light falling on it. It matters when choosing or using light sensors, automatic lights, or brightness-detecting circuits because its response speed, resistance range, and sensitivity affect how reliably it detects light levels.

photoresistor

A light-sensitive resistor whose resistance changes depending on how much light hits it. It matters for projects such as night-lights and light alarms because it gives a simple way for a microcontroller to sense brightness.

RGB

Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.

SPI

A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
