Electronic Basics #10: Digital to Analog Converter (DAC)
video description
Thanks to your video now I understand how a DAC work and how they can be created, or for what component to search if I want to have an equivalent of a PWM port!
If I want to create a VGA signal out of a pair of 65C22 or equivalent, is it the way to go? Something like the data pushed to the 65C22 then to the DAC then going into the R/G/B output (+ the rest of the signal? Or is something missing for that idea?
I'm still fairly new to electronics, so sorry if it is badly asked: /
My current goal is to display something on a VGA display out of a 6502 or 65816. I got at least the theory on how the microprocessor work, how it interact with the ROM and the RAM, I can write asm, and understand how a VGA signal is outputed to a display. But I miss somes parts in the middle to be able to connect everything together. Mostly was not sure about how to generate an analog signal from only numeric. I guess I could go for just pushing all or nothing to go for something monochrome at first, but since I do not have received any part yet, I have some time to work on the theory before playing on the breadboard. Thanks for this great video! It was really a good help to understand how DAC work!

Scott on an existing microphone connected to Alexa could you send it analog voltages to wake her up? In other words if I have a recording on my phone that plays Alexa how is the weather. If I connect an audio cable from my phone to that microphone will it work?

Is there a way to program for Arduino using assembly language? It looks like you're programming in C. I learned the basics of microcontrollers using the ATMEGA16A and assembly language last semester in college. Cool stuff

Audio voltage are not positive they are more like AC centered around 0 volts. Other use you give up 1/2 your speaker potential
