Build a Working Light Curtain Safety Gate with Arduino Uno

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

This kit lets you build a miniaturized version of an industrial light curtain—three IR beams that detect intrusion and light red when broken. It’s a hands-on introduction to array logic.

What You’ll Build

You’ll assemble three IR emitter-sensor pairs across a doorway. Break any beam, and all three red LEDs illuminate, signaling stop. Wire the LM393 comparator, then program the Arduino to scan the sensor array sequentially—just like real safety gates. You end with a functional security device.

What You’ll Learn

• Wire and calibrate IR emitter-photodiode pairs for beam-break detection.
• Use an LM393 comparator to convert analog sensor signals into clean digital levels.
• Implement array scanning logic in Arduino code to monitor multiple beams.
• Understand how industrial light curtains work and why they stop machinery instantly.
