4 bit DAC - Resistor dividers at work!
Ғылым және технология
This is no ordinary DAC.This one only has 1 resistor per bit resolution, where a regular DAC has 3 per bit :)
Less is more! I guess. I keep trying out new ways of putting my video's together. This time I just jump into the explaining without a why or conclusion. Does that work? Let's find out :)
Resistors PD0-PD3: 22000,12000,6800,3300 in ohms
Just dump a number 0-15 into port D

Aah, the good old Covox Speech Thing in "low res mode". Used to have one back in the 80's as soundcards were rare and expensive, only 8 bits but still very usable at the time.
