Attention Makers


Mini Turret-Sentry


This is my DIY project, a double barrel mini turret-sentry. It uses arduino nano as its microcontroller, a potentiometer and micro-servomotor for aiming, and an ultrasonic sensor for its sentry mode operation. Its firing mechanism is similar to the pitching machines, with a DC motor. Some parts from this project were actually salvaged parts. Like the DC motor from our old PC, the holder for the motor from a washing machine water valve, pen tubes, transparent plastic from a picture frame, a gear from a CD Drive, and a plastic bottle cap which serves as the second gear.
