DIY Logic Probe with LM358

In this video, I test a simple digital logic probe built with an LM358. The circuit uses two comparator stages to detect digital logic levels: HIGH and LOW. When the probe tip receives 5V, the green LED turns on, indicating a HIGH logic level. When the probe tip is connected to 0V or GND, the red LED turns on, indicating a LOW logic level. A simple bench test to understand logic levels, comparators, and basic digital circuit debugging.
