Ripple Tank vs MicroController Learning Lab

A simulation of a ripple tank, or wave tank. Make waves with your finger, or view examples including such wave phenomena as interference, diffraction (single slit, double slit, etc.), refraction, resonance, and the Doppler effect. Create your own experiment and save it for future reference.

MicroController Learning Lab is the ultimate interactive learning tool for anyone who wants to understand microcontrollers — from complete beginners to experienced engineers looking to sharpen their skills. Whether you are exploring electronics for the first time or building your next embedded systems project, this app gives you everything you need in one place. What's Inside: Curriculum — Structured lessons covering microcontroller fundamentals, digital I/O, analog sensors, PWM, serial communication, interrupts, and more. Learn at your own pace with clear, focused explanations. Interactive Simulators — Five animated simulators let you visualize how circuits and signals behave in real time. Watch LED blink patterns, PWM duty cycles, ADC conversions, and serial data come to life on screen. Breadboard Lab — Wire up real project circuits on a virtual breadboard. Auto-Wire builds the connections instantly. Then launch the Live Simulation to see your circuit running with animated signals and pin states. Illustrated Diagrams — 30 hand-crafted technical illustrations cover everything from pinout diagrams and circuit schematics to communication protocol timing charts. Real-World Projects — Eight guided projects show how microcontrollers are used in actual applications: soil moisture monitors, weather stations, smart relays, motor controllers, and more. Reference Library — Quick-access tables for GPIO pinouts, register maps, timing values, and common code patterns — everything you need without leaving the app. Microcontrollers Covered: ATmega328P (Arduino Uno), ATtiny85, ESP32, RP2040 (Raspberry Pi Pico), STM32 Who Is This App For: Students in electronics, computer engineering, and robotics courses. Hobbyists building their first embedded project. Engineers who want a fast visual reference on the go. No prior electronics experience required. Start from the basics and build up to real working projects.
