With the help of some very patient and considerate helpers in this forum I created a switch to turn on my 12v LED reading light panel when I sit on the chair. [ Chair Occupancy Light Switch - #12 by ec2021 ] I’m pretty much a nubie and have no intention of creating more than this one device for my …

@wvmarie - Thank you. I sure appreciate your suggestions for making this simpler for me. I dreaded the thought of trying to figure out those ATtinys especially at this early stage of my electronics education. I see the IC PC Board I've got is the yellowish brown version. I'll look for the green on…

Nano is easier as it has a USB interface. The Pro Micromini is my favourite as it's smaller and a bit cheaper, but you need an FTDI cable for programming, it has no USB on board.

Did you mean Pro mini? The Pro Micro comes with a USB-C connecter

Yes, correct, and I corrected my post above :slight_smile: All those board versions continue to confuse me at times :frowning:

@wvmarle , @blh64 , Thanks for all this info. It sounds like this'll make it much easier for me to construc the final product with this guidance. Much appreciated. Here's a big ask - Any recommendations about choosing a project case, and connectors for attaching the external sensor (seat switch), …

@ruilviana - I'm sorry. That post was how to code it and build the circuit to make it work. This post is about how to convert that into a functioning device. Should I have kept it all together? I thought they would be two distinct topics. If this should be part of the same original project, is…

[image] hfmann: thought they would be two distinct topics. I think you are right. I wouldn't bother reading the other one, but for here, be aware that there are proto shields specifically designed for Uno/Mega and handle the offset pins. Also, stay well away from the yellow brown junk perf bo…

Lots of possible cases out there. Get one that is big enough, that's the main thing. For connectors: I'm mostly using 5mm pitch screw connectors and 2.5mm pitch JST-XH style crimp connectors. Another popular choice for crimp connectors is the Molex type. They both use fine. For 12V you may also use…

[image] hfmann: and two power suppies (5 v and 12v) Why two. Much better to have 1 power supply (12V) that you have to externally connect and then use it for your LEDs and step it down for the arduino. 12V directly into the arduino will work, but is at the higher limit of input voltage. Be…

Is this the same project?

"Chair Occupancy Light Switch

If so, do not duplicate posts. Forum rule.
