Description

Broken Light Module uses digital interface 13 with LED to build a light-shielding module and simple circuit, making a light-shielding warning light. Using 13 built-in LEDs in the digital interface to connect a light saver sensor to the digital interface 3. When the light protector sensor detects a signal button, the LED will turn on; otherwise, it will be closed.
The photo interruption module triggers a signal when light is blocked between the opening of the sensor. The photo interrupter module consists of an optical emitter/detector on the front and two resistors (1 kΩ and 33 Ω) on the back.
