Ok i recently got some LED boards with some MIC5821 ics in them. They seem to use the ANODE power after a diode to feed the MIC5821 . The issue is the ANODE power is 12v... does that mean my clock/Data lines will need that voltage or can i still use a 5v micro to control? Attached are some...
I know what you mean.Especially about that Audio stuff. I love that idea. All my tvs are ROKU with web interface so i can actually do volume control via web app and mute all tvs in house... Look into it its pretty cool. TVs are cheap now also.
That helped a ton.. found the H11AA1 which is an Optocoupler, Phototransistor Output, AC Input, with Base Connection .. the info :
Seems like this little 6pin IC is just what i need. Thanks Nigel!
BTW i know itll be pulled up to my 3v3 supply instead :)
I have a AC signal coming from an outside source. The signal is 18vac and is triggered with a button. What would be the recommended way to test this signal if it has been triggered with 3v3 micro? Should i just create rectified bridge and zener to max out voltage at 3v3 or 3v... or should i do...
So when high side is 5v, the low side is pulled up and blocked by diode from high side... when high side is 0v it goes through diode and low side is 0v
