6-9 Review
On bare 6 when you measure the peak to peak voltage my understanding is that you should measure the maximum height difference, as it looks from the pictures you have only put cursours to measure the frequency and not the peak voltage. See pic
Otherwise looks good very nice explanation on part 6 of bare 6, why peak to peak voltage changed.
Bare 7 looks good.
Bare 8 looks good.
Bare 9 looks like you understood what the task was about gj! A quick tip is to use the rtic block! macro to avoid the WouldBlock error. See: https://rtic.rs/dev/api/nb/index.html
