Active Noise Cancelling Demo Kit with Arduino Due
Active Noise Cancelling Demo Kit — Engineer Real-Time Anti-Phase Noise Reduction with Arduino Due
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Bring the algorithms powering premium noise-cancelling headphones to your workbench. This kit doesn’t just teach theory — you’ll wire dual MAX9814 electret microphone amplifiers, feed them into an Arduino Due, and run code that calculates an anti-phase signal on the fly. The result is a working desktop demonstrator that visibly and audibly reduces ambient noise, perfect for engineering design showcases or Smart India Hackathon prototypes.
What You'll Build
A compact active noise cancellation (ANC) system that continuously samples environmental sound through two spaced microphones, computes a destructive interference waveform using the Due’s 32-bit SAM3X8E processor, and outputs the anti-phase signal via MCP4725 DAC and PAM8403 amplifier to a 3W speaker. The enclosed board demonstrates phase inversion, real-time latency management, and analog filtering — all on a single 9V supply.
What You'll Learn
- Program real-time audio sampling and 12‑bit DAC output on Arduino Due
- Compute anti‑phase signals using digital delay and sign inversion
- Interface MAX9814 microphone amplifiers with adjustable gain
- Design and assemble analog filtering stages with discrete resistors and capacitors

Who This Kit Is For
Engineering students pursuing B.Tech in ECE or EEE who need a hardware-based DSP capstone, final-year project, or hackathon entry. The complexity and real-time signal processing rigor match the expectations of Smart India Hackathon, IIT/NIT/VIT/BITS project reviews, and industry internships where ANC or audio DSP knowledge sets you apart.
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 launch the AI companion trained on this exact ANC demonstrator. It can walk you through wiring, code debugging, and troubleshooting over WhatsApp if you need a human touch.
Can I use this kit for my final-year engineering project submission?
Absolutely. The active noise cancellation concept is rich enough for B.Tech final projects, and the kit provides all hardware and reference code. You can extend the algorithms (e.g., adaptive filtering) to add originality.
Do I need prior experience with DSP or Fourier transforms?
Working knowledge of sampling theory and basic C programming on Arduino helps, but the companion guide explains the anti‑phase logic and signal flow clearly. The kit is designed to teach real‑time DSP hands‑on.
Can I adapt this to cancel noise in headphones instead of a speaker?
Yes. The dual‑mic front‑end and DAC output can be repurposed for a headphone ANC setup. You’ll need to modify the code for binaural processing and use a headphone driver instead of the PAM8403, but the core signal chain remains the same.
Two MAX9814 mics compute anti-phase signal. Arduino Due subtracts noise from audio output in real time.
