This project introduces you to an engaging and cost-effective way with a laser dry target system. We'll utilize an Arduino Uno microcontroller as the brain of the system, interfacing with various components to create a realistic training experience. A laser pointer acts as your virtual firearm, while a light sensor (LDR) combined with an operational amplifier (LM358) precisely detects when the laser hits the designated target. A four-digit seven-segment display (TM1637) keeps track of your hits in real-time, motivating you to improve your accuracy. To add an auditory element to your training, a buzzer controlled by the Arduino will sound whenever you achieve a successful hit, providing instant feedback. Additionally, a reset button allows you to easily clear the counter and start fresh for a new training session. This DIY laser target system offers a safe and convenient method to hone your shooting skills at home, perfect for hobbyists and target practice enthusiasts.
