Make it a TOGGLE
// WHAT YOU WILL LEARN
One press ON, next press OFF: remember a state in a variable and detect the press.
// LESSON NOTES
Part 7: make your LED a TOGGLE 🔘
Press once → ON. Press again → OFF.
The trick: a bool variable REMEMBERS the state, and ledOn = !ledOn flips it (! means NOT).
But hold the button and it keeps flipping… 😬 The fix: wait until the button is released. One press = one flip.
