Capacitor Bank Energy Storage Demo Kit with Arduino Uno – Measure Joules Stored

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Harness the sun to store energy in supercapacitors and watch exactly how many Joules flow in and out with a real-time OLED display. This kit turns abstract energy concepts into a tangible, measurable demonstration. Just connect the solar panel, the INA219 sensor, and the capacitor bank to the Arduino Uno, load the code, and you have a working energy meter that shows every Joule accumulated during charging and each Joule released when you turn on the LED.

What You'll Build

You'll assemble a solar-powered energy storage system that charges four 1-farad supercapacitors through diode-protected circuitry. An INA219 power monitor precisely tracks voltage, current, and power, while the Arduino Uno calculates total Joules stored and the OLED displays the data in real time. A white LED demonstrates the stored energy being released, giving you a complete energy cycle from sunlight to light output.

What You'll Learn

• Power and energy measurement using the INA219 sensor
• How supercapacitors differ from batteries in charging and discharging behaviour
• Reading sensor data with Arduino and displaying it on an OLED
• Practical circuit protection using Schottky diodes (1N5819)

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

If you're a CBSE Class 11 or 12 student building a physics project on capacitors and energy storage, this kit gives you everything you need with exact wiring and code. B.Tech ECE/EEE students can use it as a hands-on lab for INA219-based power monitoring, and ATL Tinkering Lab mentors will find it ideal for introducing energy concepts to young makers. It also fits neatly into Smart India Hackathon energy tracks or school-level science exhibitions.

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.
