The 5th installation of Adafruit’s adorable educational series has recently been published. “Fis for frequency”.  In this one, the ever curious Adabot starts out by asking “why do radio stations all have their own number?”. That sparks a lesson in frequency, delivered by a talking oscilloscope.

These videos are always fun, I’m looking forward to the next ones myself and always curious to see what topic they’ll choose. They’re going through the alphabet, so the next video should be “G”. What could possibly be covered in G? Ground planes?

If you haven’t had a chance to see the previous ones, you might want to check them out.
