Easy Arduino Sentry Gun

This instructable will show you how to make an easy low-cost sentry gun.

Step 1: Parts

For this project you need:

- a breadboard

- 7 jumper cables (male to male)

- Arduino Uno

- HC-SR04 ultrasonic sensor

- sg90 Servo

- Elastic pistol

Step 2: Wiring / Building Your Project

I do not have any schematic so i will describe the way of wiring:

Servo:

Ground to ground

VCC to 5Volts

Signal to Digital pin 9

Ultrasonic sensor:

Ground to ground

VCC to 5 Volts

Echo to Digital pin 13

Trigger to Digital pin 12.

Step 3: Code

If you want the code for this project, you can leave your email in the comments and i will send you it.

Step 4: Video

What's the use of ultrasonic sensor and the Bluetooth?

[Mike_Blade]

sorry for the late reply. The US sensor allows the Arduino to produce an idea of its surroundings. You can almost compare them to the "eyes" of the sentry. With Bluetooth, i assume it allows you to control it wirelessly.
