Security system from old computer mouse
Today I am going to make a security system using an old mouse...
Required things:
1. An old computer mouse
2. Mobile Charger or Battery-(5v)
3. Buzzer
Cautious :
1. Do not use battery more than 5v...If u use more than 5v it may burn your mouse circuit...The best thing is to use your old phone charger..
2. The positive end of light of mouse will go with the positive end of buzzer and negative end with the negative...
