UART Communication Virtual Lab

This simulation demonstrates UART (Universal Asynchronous Receiver/Transmitter) communication, a common protocol for serial data transfer between devices like microcontrollers (MCUs).

• It’s Asynchronous: No shared clock signal is needed; timing is based on the agreed-upon Baud Rate.
• It’s Serial: Data is sent one bit at a time over a single wire (TX for Transmit, RX for Receive).
• It uses a Frame Format: Each data byte is wrapped with Start, optional Parity, and Stop bits for synchronization and basic error checking.

Use the controls at lab to configure the UART parameters, send data between the two simulated MCUs, and observe the process!

Analog Electronıcs

Interactive PWM Signal Generator Lab

Explore how Pulse Width Modulation (PWM) works by adjusting its parameters.

Our live simulator empowers you to directly manipulate the core parameters: frequency and duty cycle. Watch the oscilloscope waveform update instantly, visualize the resulting effective (RMS) voltage, and see the direct impact on connected virtual components like LEDs and motors. It’s the ideal way to explore PWM concepts visually and build your intuition. Start experimenting now!

Circuit Theory

Kirchhoff’s Laws Interactive Lab

This virtual lab brings Kirchhoff’s fundamental circuit laws to life through real-time interactive simulations. Explore Kirchhoff’s Voltage Law (KVL) and Kirchhoff’s Current Law (KCL) by adjusting voltage sources and resistors in different circuit configurations.

Observe how voltage distributes across a series loop (KVL) and how current splits or combines at junctions (KCL). A combined simulation challenges you to apply both laws together — just like you would in real-world circuit analysis.

Perfect for students, educators, and hobbyists who want to visualize and experiment with core circuit theory concepts in a hands-on way.

Digital Electronics

Logic Gate Simulator Lab

This virtual lab allows you to interactively explore the behavior of basic logic gates — AND, OR, NOT, XOR, NAND, and NOR. Logic gates form the foundation of all digital circuits, and understanding their behavior is essential in digital electronics, computer engineering, and embedded systems.

Use this simulator to toggle inputs, observe output changes in real time, and visually reinforce your understanding of Boolean logic. Ideal for students, hobbyists, and professionals looking to strengthen their grasp on digital fundamentals.
