#AUTONOMOUS SMART SENTRY GUN SOFTWARE#
#AUTONOMOUS SMART SENTRY GUN ZIP#

The gun has a lot of momentary safety switches to prevent the gun from running without being properly closed and triggers held. Wire the button to the solder connections labelled 'DP' on the side of the board.With the mechanisms separate from the case, we can now dive into modifying the actual circuit. When the plate is shot, the sentry is disabled for 8 seconds. This usually takes the form of a small metal plate mounted on a hinge on the front of the sentry, with a button placed behind it. To fix this, you can add a disable plate. Disable Plate - in a paintball or airsoft game, the sentry can be unfair and take the fun out of a game.Wire this switch to the solder connections labelled 'RL' on the side of the board. Flip the switch back to the 'off' position, and the sentry resumes it's automatic targeting. This functionality helps when the gun runs out of ammo and you need to reload it, as it holds the gun stationary while you reload. When the switch is flipped 'on', it overrides the automatic targeting and puts the sentry gun in the 'Reload Position' - the default servo positions that are defined in the Arduino code. Reload Switch - this switch usually goes on the back of the sentry.This is also recommended if your servos draw more than 1A of current together. Leave the switch on the board in the 'off' position, and control will be transferred to your external switch. Servo power switch - if you want to add your own external switch, you can bypass the switch on the board by wiring directly to the solder connections labelled 'Bypass' on the bottom of the board.Wire the - terminal of the battery to the 'GB -' connection on the Sentry Controller.

Wire the + terminal of the battery itself to the 'GB +' connection on the Sentry Controller.Wire the black (-) wire of the battery plug to the 'GM -' connection on the Sentry Controller.Wire the red (+) wire of the battery plug to the 'GM +' connection on the Sentry Controller.With the trigger held down completing the circuit, the battery plug now provides direct connections to the electric motor inside the gun.

Use a zip tie or hose clamp to hold the gun's trigger in the squeezed position.

Find the plug that the gun's battery normally would plug into (if used in normal gameplay).

Besides eliminating the cost and weight of one servo, this gives the sentry a slightly faster response time. If you have an electric airsoft gun (or some paintball guns with electric triggers), you can replace the trigger servo with a direct electrical connection to the gun. You'll need a logic-level N-channel MOSFET transistor for this (Q1 in the schematic below). This reduces weight and improves response time. If you are using an electric airsoft gun, this allows you to wire the Arduino directly to the electric motor inside your gun, instead of using a trigger servo.

Electric trigger function - this one is tough to wire up, but very useful.

#AUTONOMOUS SMART SENTRY GUN SOFTWARE#

Fire tells when the software is firing, status shows the mode the software is running in, USB shows if the board is receiving commands via USB, and Power shows if the board is getting power via USB.

Power, Status, USB, and Fire indicator LEDs - these LED's will light up as indicators.
