A guide for installing the library and using the Arduino Multi-function Shield with code examples.
This manual explains how to install the Multi‑function Shield library, set up the Arduino development environment, and use the shield’s built‑in beeper, buttons, LED lights, digit display, and potentiometer. It also covers reading external sensors such as LM35 temperature, HC‑SR04 sonar, and MPU6050 motion sensor.
Each section provides sample code and step‑by‑step instructions, making it easy for beginners to create basic I/O projects, count pulses, and build real‑world applications like alarms, timers, and speedometers.
