Arduino 12-Bit ADC DAC Kit: MCP3208 & MCP4921 Waveform Reconstruction
Arduino 12-Bit ADC and DAC Kit: Measure, Digitize, and Reconstruct Waveforms
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
For ECE and electronics engineering students, this kit brings the theory of analog-to-digital and digital-to-analog conversion to life. You'll build a complete SPI-based measurement system that captures real analog signals, displays them on an OLED, and reconstructs the waveform through a DAC - exactly what lab manuals prescribe, but with all parts pre-tested and ready to connect.
What You'll Build
You'll assemble a working data acquisition system using an Arduino Uno, MCP3208 ADC, and MCP4921 DAC. Connect a potentiometer to vary the input voltage, watch the 12-bit digital readout on the OLED, and see the DAC reproduce the waveform in real time. It's a compact, debugged setup that mirrors the lab assignments in ECE curricula.
What You'll Learn
- SPI bus communication and multi-device connection
- 12-bit ADC configuration and reading analog voltages
- 12-bit DAC output and waveform generation
- Data visualization on OLED displays

Who This Kit Is For
This kit is designed for ECE and EEE students in B.Tech programs at universities like IITs, NITs, VIT, BITS, and state engineering colleges. It fits directly into ECE Lab curricula for courses on data converters and microcontrollers. CBSE Class 12 students exploring embedded systems for science exhibitions or Smart India Hackathon participants will also find it a ready-to-use module.
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?
Simply scan the QR code on the box to chat with the AI build companion trained on this exact project. If you need human help, WhatsApp us at the number provided - we're an Indian startup and respond quickly.
Can I interface these chips with a Raspberry Pi instead of Arduino?
The MCP3208 and MCP4921 use standard SPI, so they work with any microcontroller or SBC like Raspberry Pi. However, this kit's step-by-step build guide and AI companion are tuned for Arduino Uno. If you're comfortable adapting SPI code, you can definitely use it with a Pi.
What kind of waveforms can I generate with the DAC?
The MCP4921 DAC can produce arbitrary waveforms programmed via the Arduino - sine, square, triangle, and even audio signals. The kit includes sample sketches to output a sine wave and vary its frequency.
How is this kit useful for ECE lab exams?
This kit covers the exact ADC/DAC interfacing experiments prescribed in many Indian university ECE lab manuals. By building it, you'll master SPI communication, understand 12-bit resolution, and be well-prepared for viva and lab assessments.
