Real-Time Oscilloscope on 2.4in TFT – Advanced Kit with Arduino Mega

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

Turn your Arduino Mega into a fully functional digital oscilloscope. This kit equips you with a high-quality MAX9814 microphone amplifier and a vibrant 2.4‑inch ILI9341 TFT screen, so you can visualize sound patterns, sensor outputs, or any voltage signal in real time. Two potentiometers let you fine‑tune the timebase and trigger level, mimicking the controls of a professional bench instrument.

What You’ll Build

A compact, battery‑powered oscilloscope that captures and displays voltage waveforms from 0–5V, with a trigger‑stabilized trace and adjustable horizontal sweep. You can plug in the MAX9814 to see your voice as a waveform, or connect any analog sensor to monitor its output live. The bright 2.4‑inch colour display shows crisp, animated graphs with grid lines, just like a commercial scope.

What You’ll Learn

• ADC sampling and circular buffer management on the Arduino Mega
• Driving the ILI9341 TFT display with the TFT_eSPI library for fast, flicker‑free graphics
• Implementing software‑based trigger detection and timebase scaling using potentiometer inputs
• Filtering and signal conditioning with the MAX9814 amplifier and passive components
