I'm working on python code with a raspberry pi pico with circuitpython on the mu editor. I have a speaker linked to GP15 (please ignore all the LED items) but I can't seem to make the speaker beep or make any sound multiple times. I am unsure what I'm doing wrong. What I want: the speaker to beep multiple times in intervals of 1 second each time the for loop happens. Also just please explain to me how to utilize the commands for the speaker. I am confused
