Laser Light Alarm Circuit using Arduino

Last updated on 1 July 2026 by Admin-Lavi Leave a Comment

This article is for simple Laser Light Alarm Circuit using Arduino. A laser light shines on an LDR and when someone blocks the laser beam, the LDR changes its value and then Arduino reads this change and turns ON the buzzer to make alarm sound. A reset button stops the alarm. Also, the system uses […]
