Introduction to Electronics in Everyday Products
Electronics play a crucial role in modern products, enabling functions such as sensing, timing, switching, and controlling outputs.
Understanding how electronics work in products helps designers create more efficient and innovative solutions.
DefinitionElectronicsThe branch of science and technology concerned with the design and application of circuits and devices using electricity.
ExampleThink of a smartphone - it uses sensors to detect touch, timers to manage processes, and controllers to manage power usage.
AnalogyElectronics in a product are like the nervous system in a body, sending signals and controlling actions.
