A quick follow up update based on what's happened in initial testing.
To begin with the string snapped on the claw which is a simple fix, of which the reason why I haven't changed to a stronger string is that it acts a bit like a fuse so instead of causing the motor to burn out.
However to improve I'm going to in the future add some code in to make it so it should be able to instead use a timer to prevent this from happening.
After about an hour of people playing on it the claw just stopped working, of which I found it to be unfortunately the power supply went pop which unfortunately meant that it stopped working.
That's it for this quick update!
