Raspberry Pi is a low-cost single-board computer running Linux, used for IoT projects, home automation, robotics, and prototyping. Makers, hardware engineers, and embedded developers use it to learn electronics and quickly test ideas. Learning time: 3–4 months. Salary impact: Medium, higher in hardware/IoT roles. Adjacent: Arduino, Embedded Linux, IoT Fundamentals, Python.
Raspberry Pi is a credit-card-sized single-board computer that runs Linux and gives you full programmable control over GPIO (General Purpose Input/Output) pins. You can wire sensors, motors, LEDs, and switches, then write code to read data, make decisions, and control hardware. It costs $35–$75 and consumes minimal power, making it ideal for long-running IoT devices, home automation hubs, and embedded projects. Raspberry Pi projects range from simple (blinking an LED) to complex (a home weather station with cloud data sync, a robotics platform, or a Kubernetes cluster). The ecosystem includes thousands of tutorials, libraries, and compatible hardware.
