Exercise 18 - Applications & implications(Project Notes)
This project is inspired by this alarm gun.
1. What will it do?
My project is about a target and laser gun. When the shooter accurately aims and fire at the target, the target will fall.Who's done what beforehand?
- Some of the project uses photo resistors as sensors and some using ir receivers.- Some articles on this are available in Instructables

What tasks needs to be completed?
- Understanding and testing of Phototransistor
- Servo motor control
- Design and construct microcontroller boards
- 3D design of target board and mounting for servo
- 2D design of chasis of house microcontroller
What questions need to be answered ?
- What is the codes to trigger the target?- How much power is needed to operate this project?
- Will the chasis topple when the servo moves?
What is the schedule ?
- 29 May - test circuit on Arduino- 30 May - Design target board with Inventor
- 31 May - Design microcontroller board
- 1 June to 14 June - Fabricate PCB, laser cut and 3d print
- 15 June to 21 June - troubleshoot, testing, document
- 22 June - Presentation
How will it be evaluated?
- Success trigger of servo when user shoot at the middle of the target.
