TFT Touch Oscilloscope 2-Channel Kit with Arduino Mega
Build Your Own Dual-Channel Oscilloscope with Arduino Mega and TFT Touchscreen
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 an Arduino Mega into a functional dual-channel oscilloscope that captures and displays signals at 50kHz. Perfect for analyzing audio circuits, sensor outputs, and low-frequency electronics projects—right from your workbench. The 2.4-inch TFT touchscreen plots dual waveform traces in real time, while tactile controls let you adjust trigger level, timebase, and voltage scale with precision.
What You'll Build
A portable, battery-powered oscilloscope with two independent input channels. You'll route signals to the Arduino Mega's ADC pins, write the sampling firmware, and render waveforms on the ILI9341 display. Adjustable trigger thresholds and sweep speeds make it a genuine measurement tool for debugging mixed-signal circuits, verifying PWM outputs, or exploring AC waveforms in school and college labs.
What You'll Learn
- Sampling analog signals with the Arduino Mega's 10‑bit ADC at up to 50kHz per channel
- Driving a 2.4‑inch ILI9341 TFT display for real‑time waveform plotting and UI elements
- Implementing hardware trigger and timebase controls with tactile buttons and potentiometers
- Designing a complete embedded instrumentation system on a breadboard, including power management

Who This Kit Is For
This intermediate kit is ideal for CBSE Class 11‑12 students exploring microcontroller-based instrumentation, B.Tech ECE/EEE undergraduates prototyping test equipment, and participants in Smart India Hackathon who need a custom signal analyzer. Makers in ATL Tinkering Labs and engineering clubs at IIT, NIT, VIT, or BITS Pilani will gain hands‑on experience with real‑time embedded systems and display integration.
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.
What if I get stuck during the build?
Scan the QR code to open the AI companion; it knows every component and step of this kit. You can also reach us on WhatsApp for direct support within hours.
Can I view two signals at the same time?
Yes, the kit is designed for true dual‑channel operation. Both channels are sampled simultaneously and displayed as overlaid or separate traces on the TFT.
What is the maximum frequency I can measure?
With a 50kHz sampling rate per channel, you can reliably capture signals up to about 20kHz, plenty for audio work, sensor signals, and most hobbyist projects.
How do I control the oscilloscope – via touchscreen?
Waveforms are displayed on the TFT, but physical controls (three tactile buttons and two potentiometers) handle trigger level, sweep speed, and voltage scaling for a responsive, glitch‑free interface.
Arduino Mega samples two ADC channels at 50kHz. 2.4in TFT shows dual trace with trigger control.
