Two Channel Oscilloscope Kit with Arduino Mega
Two Channel Oscilloscope Kit with Arduino Mega — Bring Dual-Trace Waveform Analysis to Your Workbench
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 genuine dual-channel oscilloscope that samples at 50 kHz and renders waveforms on a colour TFT screen. You’ll solder the ADS1115 ADC, buttons, and potentiometers onto a prototype board, load the firmware, and instantly have a portable instrument for debugging sensor outputs, audio stages, or microcontroller signals. Each trace can be scaled in time and voltage, the trigger stabilises repetitive waveforms, and on-screen cursors let you measure voltage and time intervals exactly like a bench scope.
What You'll Build
After assembling and flashing, you’ll hold a complete measurement tool. Connect two test points from any low‑voltage circuit, adjust the two 10kΩ pots to set volts/div and time/div, and watch dual traces sweep across the 1.8‑inch ST7735 display. Four tactile buttons let you move cursors, toggle channels, and freeze the display. The result is a responsive, portable scope that runs from a 9V battery and fits in your tool bag—ideal for field work or a cluttered bench.
What You'll Learn
- Configure the ADS1115 16‑bit ADC over I²C and achieve two‑channel 50 kSps real‑time sampling with the Arduino Mega.
- Write circular‑buffer data acquisition code that captures a full waveform buffer without missing samples.
- Drive the ST7735 TFT via SPI to draw graticules, moving traces, and on‑screen measurement cursors.
- Implement edge‑trigger logic that re‑arms after a hold‑off period, just like a commercial oscilloscope.

Who This Kit Is For
B.Tech ECE and EEE students who need a reliable mini‑project for embedded systems lab will find this scope a staple on their breadboard. CBSE Class XII physics students can use it to visualise alternating current waveforms and RC charging curves. Smart India Hackathon teams building sensor‑driven prototypes, ATL tinkering labs introducing instrumentation, and members of makerspaces at IITs, NITs, VIT, and BITS Pilani will all appreciate a scope they built and can troubleshoot themselves.
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?

What is the maximum input voltage this oscilloscope can measure?
The ADS1115 inputs accept voltages from -0.3V to VDD+0.3V, so with a 5V supply you can safely measure signals up to ±5V relative to ground. Use a 10x attenuator probe (not included) for higher voltages.
Can I use this kit for audio frequency work?
Absolutely. The 50 kHz sampling rate per channel captures audio band signals cleanly, making it perfect for viewing dual-channel Lissajous patterns, amplifier outputs, or microphone signals.
Do I need an external programmer or additional cables?
No extra hardware is required beyond a USB cable (the Arduino Mega programs over USB). The kit includes all components, soldering iron, and solder; you just need a computer with the Arduino IDE installed.
Arduino Mega samples two ADC channels at 50kHz. TFT shows dual trace with trigger and measurement cursors.
