Trying to find a schematic
Posted: 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
