IoT Circuits and Electronics
Stub. The foundations of electricity and circuit design needed to build IoT devices, worked through four use cases — something that lights up, something that uses electricity, something that moves, something that observes — and a survey of useful circuits.
Before an IoT device can run any software, it has to exist as a physical circuit. Covers the basics of electrical circuit design (voltage, current, components) and then four concrete use cases that recur in almost every device: an output that lights up (LEDs), a load that consumes power (motors, heaters), an actuator that moves (motors, servos), and a sensor that observes (transducers) — plus a grab-bag of other useful circuits (voltage dividers, protection circuits, etc.) that show up across designs.
