INA219 Power Monitor Display Kit with Arduino Uno + LED
INA219 Power Monitor Display Kit with Arduino Uno: Live Voltage, Current & Power Monitoring
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Ever wondered how much power your batteries or small solar panels really deliver? This kit lets you build a portable power monitor that measures voltage, current, and power simultaneously and displays them live on a bright OLED screen. It’s a perfect hands-on tool for science projects, ATL tinkering, or understanding energy in a tangible way.
What You'll Build
You’ll assemble a compact monitoring station on a 400-point breadboard. The INA219 sensor reads voltage (up to 26V) and current (up to 3.2A) and computes power; all three numbers update every second on the 0.96-inch OLED. Use it to test 9V batteries, USB power banks, small solar cells, or any low-voltage DC source—ideal for CBSE science experiments or just satisfying your curiosity about energy flow.
What You'll Learn
- Interfacing the INA219 power monitor sensor over I2C with Arduino Uno
- Programming the Arduino to read voltage, current, and power values from a library
- Driving an OLED display to show live data (using U8g2 or similar)
- Wiring a complete measurement circuit on a breadboard reliably

Who This Kit Is For
This kit is perfect for school students exploring electronics, ATL Tinkering Lab participants, and CBSE Class 11-12 students building science projects. It’s also an excellent first tool for B.Tech freshmen in ECE/EEE who need a quick power monitoring setup for hostel experiments or Smart India Hackathon prototypes.
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 kit. If you need human help, WhatsApp support is included with every purchase.
Is this kit safe for a 10-year-old?
Yes. The circuit operates at low voltage (9V battery max) and all connections are on a solderless breadboard. Adult supervision is recommended for complete beginners.
Can I use it to measure power from a solar panel?
Absolutely. The INA219 handles up to 26V and 3.2A, so small solar panels work perfectly. Just connect the panel’s output to the INA219 input terminals.
Do I need any prior programming experience?
No. The kit includes pre‑written Arduino code that you upload with one click, and the AI companion explains every line if you’re curious to learn more.
INA219 measures voltage, current and power simultaneously over I2C. OLED shows all three values live.
