Arduino Lissajous Pattern Generator Kit – Draw Real-Time Waveform Curves on Paper

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Transform two precise SG90 servo motors into drawing instruments that trace elegant Lissajous figures on paper. By driving each servo with independent sine waves of tunable frequencies, you watch interference patterns emerge physically—a direct demonstration of how waveforms combine that no simulation can replace. This kit turns abstract signal theory into an interactive plotting engine for engineering labs, physics projects, and data visualization capstones.

What You'll Build

A two-axis drawing machine where servo-mounted pens map sine waves onto a flat surface. Two onboard potentiometers let you sweep frequency and phase in real time, while the 0.96-inch OLED displays the current parameters of both channels. The resulting paper trace is a permanent Lissajous curve, showing how the frequency ratio and phase shift define the shape.

What You'll Learn

• Precise servo positioning using Arduino PWM signals to convert electrical angles into mechanical movement
• Generating and tuning sine wave outputs in code to drive two actuators independently
• Reading analog potentiometer values to modify frequency and phase on the fly without a computer
• Displaying real-time waveform parameters on an I2C OLED screen for live monitoring and calibration

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

B.Tech ECE and EEE students exploring signal processing and control systems, physics undergraduates building wave interference experiments, and Smart India Hackathon participants who need a ready-made demonstration platform. Also fits IIT/NIT/VIT/BITS engineering labs where accurate, repeatable visualization of waveform interactions is required without sourcing components from multiple vendors.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
