Introduction: Laser Shooting Game

This laser game is a simple project that utilizes an Arduino mini. All target boards have an Arduino, sensors, and servo control ports. Shooting the target center triggers the servo and the board falls flat.

Step 1: Step 1:What You Need

Bill of material:
1. Shooting Target board PCB (attached gerber file)
2. Servo
3. Photo diode x 3
4. IR transmitter x 1
5. IR receiver x 1
6. 9014 NPN transistors x 3\
7. Pins and socket
8. Arduino Mini x 2
9. SMD components (Caps, resistors)
10. CD
11. Target board graphic (CD size)
12. Toy laser gun

Step 2: Step 2: Soldering

Assembly all components on the PCB.

Step 3: Step 3: Prepare the Target Board

Cut out the and stick it on the CD by glue
The diameter of the CD is 120 mm and the inner diameter is 15 mm.

Step 4: Step 4: Glue the PCB on Servo Arm

Use the hot glue gun to glue the assembled PCB on the servo arm.
Please reserved some space between the servo and the PCB. As the servo chassis may collide with the PCB during servo arm moment.

Step 5: Step 5: Stick the Target Board on the PCB

Use hot glue gun to glue the CD (target board) on PCB

Step 6: Step 6: Tidy Up the Cable

Connect the servo with the PCB.
Shorten the servo cable or tide the cable with string.
Please reserved some cable length for servo movement.

Step 7: Step 7: Upload the Firmware

1. Install the IR remote library and complie the arduino program
2. Upload the firmware to Arduino mini

Step 8: Step 8: Modify the Laser Gun

1. Open the laser gun
2. Cut out the PCB
3. Replace the PCB with Arduino Mini
4. Solder the power wire to Vin and GND
5. Solder the laser diode wire to Pin 3 and GND
6. Solder the sound trigger wire to Pin 13
7. Download the firmware to arduino mini

Step 9: Final Step: Make More Target Boards and Enjoy the Game
