Starter Kit project 12 Knock Lock does not 'relock' after being opened

In the firsts prints of the book, the code shown had a typo where the “knock counter” variable was not reset to 0 after the first “unlock”, hence this issue would happen.

Code

Code example with "numberOfKnocks = 0" highlighted

This issue is fixed in the IDE example, but it’s worth to check before uploading to your board.
