A Logic Probe is a handheld testing device used to diagnose and troubleshoot digital circuits by detecting and displaying the logic state (HIGH, LOW, or pulsing) of a circuit point. It is commonly used in electronics repair, development, and testing of microcontrollers, logic gates, and digital ICs.
The logic probe features LED or digital indicators to show the status of the signal being tested. It can quickly identify issues like stuck-at faults, missing pulses, or incorrect voltage levels in digital circuits. Designed for ease of use, the probe connects to the circuit under test and provides instant feedback, making it an essential tool for engineers, technicians, and hobbyists working with digital electronics.
