INA219 Power Monitor Starter Kit Kit with Arduino Uno + Sensor
INA219 Power Monitor Kit with Arduino Uno – Live Wattage 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.
Curious about your gadgets’ power consumption? Build a live power monitor that displays voltage, current, and wattage on an LCD. This kit introduces I2C sensor communication and real‑time measurement—perfect for beginners.
What You'll Build
A working power meter that reads DC power from any source (0–26V) and updates a 16x2 LCD every second. You can test batteries, USB chargers, and small motors to see live power draw and better understand energy use.
What You'll Learn
- Connecting an INA219 sensor over I2C to Arduino Uno
- Reading voltage, current, and power with simple Arduino code
- Driving a 16x2 LCD through an I2C backpack for clear readouts
- Observing real‑time power changes and linking them to device behavior
