Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- DIP switch
- A DIP switch is a small set of physical on/off switches used to configure hardware settings without software. It matters because changing features such as auto power-on or charging limits may require moving these tiny switches correctly.
- 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.
