Automatic IC Tester Kit with Arduino Mega + LED
Build Your Own Automatic IC Tester with Arduino Mega & OLED – Verify 74xx and 40xx Logic Gates Instantly
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Instead of building a separate test circuit for each logic gate IC or probing with a multimeter, you'll construct a standalone automatic tester that plugs any 74xx or 40xx series chip into a ZIF socket, runs truth-table verification via Arduino Mega and shift registers, and instantly displays "PASS" or "FAIL" by gate on the OLED screen. This kit transforms a tedious lab task into a one-click operation, making it a must-have for electronics workshops, repair benches, and student labs.
What You'll Build
A handheld, battery-capable IC tester that accepts DIP ICs up to 16 pins, auto-identifies pin configurations, and sequentially tests each logic gate. You'll own a reliable lab tool that eliminates guesswork when sorting mixed or salvaged ICs, and it's expandable to more logic families. The clear OLED feedback ensures you know instantly whether an IC is functional or faulty.
What You'll Learn
- How shift registers (74HC595 and 74HC165) expand digital I/O for parallel testing
- Interfacing an I2C OLED display to show real-time test results
- Writing truth-table verification logic in Arduino C/C++ for multiple logic families
- Designing robust test fixtures with ZIF sockets and debouncing techniques

Who This Kit Is For
CBSE Class 11–12 students pursuing physics or computer science practicals, B.Tech ECE/EEE students prototyping digital electronics labs, Smart India Hackathon participants building test automation tools, and ATL Tinkering Lab facilitators teaching logic gate fundamentals will find this kit directly applicable. It bridges textbook concepts with a practical instrument that stays on the workbench long after the build is complete.
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 chat with the AI companion trained on this exact project; it will diagnose your issue step-by-step. For complex edge cases, you can also WhatsApp images to our support team.
Can I test logic ICs other than 74xx and 40xx series?
The firmware is pre‑flashed for 14‑pin and 16‑pin 74xx and 40xx logic gates. You can modify the truth table arrays in the Arduino code to test other TTL/CMOS families with matching pinouts.
Do I need soldering experience?
Yes, this kit involves soldering through‑hole components onto the prototype boards and wiring up the ZIF socket. The included 25W iron and lead‑free solder are adequate for beginners; the AI companion will guide you on proper joint techniques.
How is the tester powered?
The kit includes a 5V 1A power supply that plugs directly into the Arduino Mega’s DC jack. For portable use, you can connect a 7–12V battery to the barrel jack or Vin pin.
ZIF socket with shift registers tests 74xx and 40xx logic gates automatically. OLED shows pass or fail by gate.
