Phase Locked Loop Analyser Kit with Arduino Mega
Phase Locked Loop Analyser Kit with Arduino Mega – Build an Instrument to Sweep and Measure CD4046 Lock Range
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit lets you build a fully functional phase locked loop analyser that sweeps input frequencies with an AD9833 DDS module and measures the CD4046 PLL's lock range, displaying acquisition and lock regions on a 1.8-inch TFT. Designed for advanced electronics students and makers, it transforms theoretical PLL concepts into a hands-on measurement tool you'll use in lab projects and signal processing experiments.
What You'll Build
You'll assemble a standalone PLL analyser that automatically sweeps frequencies, detects when the PLL locks, and plots the lock-in and hold-in ranges on the TFT. The finished instrument connects via USB for data logging and can be reused for testing other PLL circuits, making it a permanent addition to your workbench.
What You'll Learn
- Generate precise frequencies up to 12.5 MHz using the AD9833 DDS module
- Read analog voltage with 16-bit precision using the ADS1115 ADC to determine lock condition
- Implement a sweep-and-measure algorithm on Arduino to map lock range boundaries
- Characterize phase locked loop parameters like capture range and lock range, essential for communication systems

Who This Kit Is For
This advanced kit is built for B.Tech ECE and EEE students tackling communication labs, final-year projects, or Smart India Hackathon challenges involving frequency synthesis. It's equally valuable for makers prototyping RF test gear and for ATL Tinkering Lab mentors demonstrating closed-loop control systems. If you've worked with Arduino before and want to transition from blinking LEDs to real instrumentation, this is your next step.
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?
Use the AI companion via QR code for instant, context-aware guidance, or message us on WhatsApp for backup support.
Can I extend the analyser to test other PLL chips beyond the CD4046?
Yes, the Arduino code is modular – you can adapt the frequency sweep and lock detection logic for 74HC4046 or discrete PLL circuits with minimal changes.
Is this kit suitable for a B.Tech final-year project submission?
Absolutely. The kit provides real measurement data that you can document as a complete instrumentation project, and the AI companion helps with code and theory explanations.
Do I need any additional lab equipment to use this kit?
No external oscilloscope is required – the built-in TFT displays lock range directly. A multimeter is helpful but not essential; the ADC reads analog voltage for you.
