Project 2- Smart fire extinguisher

PROJECT 2 ENGR 6

Smart fire extinguisher- Consist 3 sensing mode: temperature, time, and fluid level in percentage. It first display menu so user know what output to select from, then once "select" button is pressed, it trigger the servo which move back and forth of the spray bottle. And LCD display how long it takes and fluid level of bottle.

*In the beginning, we decided to use rubber bend to connect between servo and spray bottle. However, it stretch too much, which it's hard to press the bottle handle.

* Then I decided to use soldering iron to connect servo and bottle handle. However, it break too easily when servo stretched. 

*Then I used floss wires to connect servo with handle because the tendency of strength. And it works well, but the soldering iron is still too weak, and break too easily. 

*Finally, I used copper wires to connect to handle, and rubber bend on top so it require less force to pull it. 

* It's able to display menu and changing according to buttons. 

* TA DA DA!!!
