Building a Sentry Gun with Laser Trip Wire System and Arduino


Step 7: Setting Up for Action!

Picture of Setting Up for Action!
Place the LDR sensor at one end and laser at the other end.
Make sure the LDR is calibrated and the laser is pointing at it.

This video shows the gun turning to the preset angle when my hand block the LDR from sensing the laser.

Gun In Action:
This video shows the gun moved to the preset angle and trigger being pulled when the trip-wire system senses an obstacle.
