Arduino TFT Oscilloscope Kit with Arduino Mega
Build a 50kHz Oscilloscope with Arduino Mega and TFT – Complete Kit
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 an Arduino Mega into a fully functional handheld oscilloscope that captures signals at 50kHz and renders them on a crisp 2.4-inch TFT screen. With trigger level, timebase controls, and a portable 9V battery design, this kit delivers a benchtop instrument experience in a project you build yourself. It’s ideal for debugging sensor circuits, visualising audio waveforms, or understanding signal acquisition in a real embedded system.
What You'll Build
You’ll assemble a portable oscilloscope that samples analog inputs at up to 50kHz and displays the waveform on the ILI9341 colour TFT. Four tactile buttons and two potentiometers let you adjust trigger level and sweep speed on the fly. The final device runs off a 9V battery and fits on a prototyping board you solder yourself—ready to move from lab bench to field testing.
What You'll Learn
- Sampling analog signals with Arduino’s ADC at high speed using optimised code
- Driving an ILI9341 TFT display over SPI for fast, flicker-free waveform plotting
- Implementing trigger-level detection and timebase control in firmware
- Soldering and assembling a compact electronics prototype on a perfboard

Who This Kit Is For
This kit is built for B.Tech ECE and EEE students who need a portable test instrument for mini-projects and Smart India Hackathon prototypes. It’s also perfect for IIT/NIT/VIT/BITS engineering labs and advanced ATL tinkering spaces. CBSE Class 12 science students with soldering experience will find it challenging and deeply rewarding.
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 on the box to access the AI companion built just for this oscilloscope kit. It walks you through each step, and you can also message our support team on WhatsApp for human help.
Does the kit include a 9V battery?
The 9V battery snap is included, but the battery itself is not. You’ll need a standard 9V battery (alkaline or rechargeable) to power the scope portably.
Can I measure signals faster than 50kHz?
The kit is calibrated for educational use and reliably samples up to 50kHz. For higher frequencies you would need a faster ADC, but the concepts you learn here—triggering, timebase, and display—apply to any oscilloscope design.
Can I modify the firmware to add features like FFT or voltage readout?
Absolutely. The Arduino sketch is open source and fully modifiable. Ask the AI companion for guidance on adding an FFT or a voltage measurement overlay; it knows the code structure and pin mapping.
2.4in TFT renders waveforms sampled at 50kHz with trigger level and timebase controls.
