Kuan: watch dog (working in progress)

Watch dog is a device that can gurd your life in multiple ways. That’s how it works, firstly, you put something on the disc , and whenever anyone trying to take the thing away, it automaticly turn on the watch dog and starting shooting paper balls at that person.img_1073

So for start , i want to use a photo resister as the input device, and i found its hard to use it in the dark , and it’s really delicate.

So i changed it in to a level switch. which is easier to handel .

For the out put part, i use two leds, one toy motor, one toy luncher kit, mutiple gears, one servo motor and multiple resisters.
