摘要：This project depends up on the automatic gun firing by using ARDUINO board. We are placingLM293D motor IC It will rotate at an angle of 180 degrees. The ultrasonic sensor will transmit a sound waves, ifenemy present at an angle of 180 degrees. The transmitted signal is hitted to an object and produce an echo signal backto the ultrasonic sensor. The ultrasonic sensor will send the pulse to an ARDUINO board. The ARDUINO board sendthe instruction to the gun, then the gun automatically starts firing. The distance of the object will show in the LiquidCrystal Display (LCD).
