Objective
A prototype for a trick and treat Jack-O Lantern filled with candies. When reaching inside to get candies sonar sensor would trigger loud scary sound and bright pulsating LED strip.
Execution
- The volume of mp3 could not increase
- The sonar sensor fluctuates and readings would not detect hand at close proximity and could not insert fully into container
- The 9v power source could not power mp3 and LED strip without distorting sound
Resolution
- A more accurate sonar sensor that can register movement within the container
- Regulate voltage input to play mp3 and LED strip in 1 code and 1 power source
- Control and Increase sound volume
