Test Your Fate: Sound

In order to see if sound could be incorporated within the pinball machine multiple avenues have been explored.

Mirco:Bit:
Upon researching different methods of coding sound such as ardunios and raspberry pi circuit boards a simpler version aimed at children was used.  Although the software provided with the micro:bit is simple to use and understand there where limitations as to what could be achieved with the software provided. This lead to multiple experiments seeing if the exisiting code could be adapted to work for the purpose of the pinball machine.  Initially code using the motion/light sensor built into the board was explored however this couldn't be adapted to create sound only to show a message using the LED lights within the board (see figures 1-4). In addition the motion sensor was also explored to see if when the ball rolled past or over sound could be created however this didn't work either (see figures 5-6). Further tests creating circuits inspired by fruit keyboard (see figure 7) where conducted however this wouldn't be possible to implement within the pinball machine. After multiple attemtps I think a less techincal approach is needed as the circuit board is too limtied for the functions needed (see figure 8).

Bells:
In addition to circuit boards, more mechanical options were explored. Services bells have been looked at to see if they would ring once the ball drops through the holes (see figure 9). This method works however is very unpredictable as the ball doesn't tend to fall straight down meaning sometimes it hits and other times it roles down. Therefore after exploring multiple options for sound the original idea of using a speaker will be implemented as this allows for the most reliable option that will enhance the playing process.
