Trying to find a schematic

#1 Post by dynamicdave » 11 Apr 2019, 20:59

I'm trying to find a schematic circuit that was published on this forum a couple of months (or so) ago.

It contained a Wemos D1 Mini, a PCF8574, a NE555-based device to create an interrupt, some MOSFETS and optocouplers.

I can't remember what the project was called and can't find it after searching through the various sections on this forum.

If anyone can remember the schematic I'm talking about and has the link - I would be very grateful.

I've bought most of the above components as I was going to build a similar project.

Kind regards from David

I did an image dump of the forum (spanning Jan-2018 to Apr-2019) and could not find anything that matches your description. Here's a link so you can investigate:

Thank you Patou - that's the schematic-graphic drawing I was looking for.

Thanks for sharing the link with me again.

Kind regards from David.

Hi Thomas,
Thanks for taking the time to look for me.

Here's the link to the schematic-graphic that I was looking for.

It's strange it did not show-up in your search on Google.

Indeed. Glad to see that the mystery drawing was found.
