Introduction to Power Time Logger

The Power Time Logger is a specialized electronic project designed to monitor and record the power on/off cycles of USB-powered devices over a period of 365 days before it automatically resets. Built around the Arduino UNO and the DFRobot 1602 LCD Keypad Shield, it captures the total time a device is powered on and the total number of on/off cycles. The project includes a simple yet effective user interface that allows users to switch between viewing the total on/off cycles and the cumulative on time. It also offers a reset function for program data. This device is particularly useful for tracking the usage of devices like Wi-Fi routers, 3D printers, computers, or any other equipment powered through a USB port. By providing this data, users can gain insights into device usage patterns, potentially informing decisions about energy consumption, operational efficiency, and device lifecycle management.
