You can measure DC Voltage, Current and Power in a voltage range from 0V to 26V. This circuit use a high-side current shunt and power monitor with an I2C interface INA209 from Texas Instruments and an Arduino UNO as microcontroller. The values are shown on a 2x16 LCD display.
This article describe the use of the INA209 Arduino Library to control a Texas Instruments INA209 through I2C BUS communication with Arduino open-source electronics prototyping platform.
