Arduino UNO R4 Lesson 42 Active Buzzer sending an SOS

Nice Solution! I like the on/off slide switch for the buzzer. Also nice touch with the Display. Great to visualize things. Kind Regards from Calgary Alberta Canada.

H James I like your little screen and also how you can turn the annoying buzzer off. Unfortunately, you've got your timings wrong. dah should be on for 3 units and off for 1 unit. Also, you turn the buzzer off for 1 unit at the end of dit and for 3 units (should be 1 unit as I said above) at the end of dah, therefore the delay after each letter should be 2 units. This is probably why you found it hard to hear the pause between each 'sos'. If you fix these bugs, I think that a delay of 7 units would work fine. Obviously this should be coded as 6 units because of the i unit delay at the end of the last dit in 'sos'. Sorry to be so negative😿😿

Not negative, just informative. Made those changes and it worked perfectly. Thanks
