DIY Power Meter Project with INA226 and ATtiny85

By admin

This page details a DIY project for hams to create a voltage, current, and power meter using the INA226 chip, controlled by an ATtiny85 and displayed on a 128X32 OLED screen. The project includes calibration factors and resistor values to determine current range and resolution. Instructions are provided for setting up the project on a breadboard with an Arduino Uno and transitioning to the final build with an ATtiny85. The article demonstrates the feasibility of using an ATtiny85 microcontroller for controlling the power meter project.
