Creative video, keep it up, thank you :)

Very well-put-together presentation. Looking forward to more of these. Cheers!

I just bought this book a few days ago and can't wait until it arrives. I am new to electronics and I really hope to learn some basics from it. Nice video!

You show the reset button connected across the supply rails at 16:00...

Ah good spot. Thanks. This is the danger of creating simplified versions of the circuit diagram. In the full circuit diagram the connection to the ground rail does have a pull down resistor, which is omitted here. I'll add a note to this effect in the description.

Hmm are you sure it doesn't mean diode?
