Ohm's Law Interactive Demo Kit with Arduino Uno - Live Voltage, Current, Resistance Display

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

Build a hands-on demonstration of Ohm's Law that brings textbook theory to life right on your breadboard. By varying a potentiometer, you'll see voltage and current readings update instantly on the LCD, while the Arduino Uno calculates resistance in real time. Whether for a school science exhibition, a CBSE practical lab, or an ATL tinkering session, this kit turns abstract formulas into a tangible, interactive experiment.

What You'll Build

You'll assemble a self-contained circuit that uses a voltage sensor and an ACS712 current module to measure electrical parameters across a 10k? resistor. The Arduino reads these values, computes resistance using Ohm's Law, and displays live V, I, and R on a 16x2 LCD with I2C backpack. The entire project fits on a standard 400-point breadboard-no soldering, no extra tools. In under three hours, you'll have a polished demo that can be reused for multiple experiments.

What You'll Learn

• Wire a sensor circuit on a breadboard using jumper wires and understand the physical layout of components.
• Read analog sensor data from a voltage divider and an ACS712 current sensor, then convert raw ADC values into volts and amperes.
• Implement I2C communication to drive a 16x2 LCD display, showing multiple variables simultaneously.
• Verify Ohm's Law experimentally by observing that R stays constant while V and I change proportionally.
