Last weekend I spent my time configuring the Raspberry Pi 3 Model B to trigger a relay. Tonight, I finally took the time to solder the 2 x 20 pin headers to the Raspberry Pi Zero W board. I wired it all up again and took a photo with a quarter coin, so you can appreciate how small the circuit is.
I had to make a minor software adjustment, because the Node.js version that I installed on the Pi 3 did not work. Apparently I had to get the armv6l version instead of the arm7l.
After a quick re-install from the above link, I was back in business.
Now I’m going to test the stability of the WiFi on the Pi Zero, before I make the final security touches to the software and then to the garage door opener!
