My goal was to control light under stairs I built for my daughter using the system VoffCon to handle the commands via the internet.
This is an image on how I connected the 12V light strip. I used three BC547 (see datasheet) to control the colors on the strip
The code running on the NnodeMcu(esp2866) is the default DeviceServer with little pin mode modifications.
I wanted to use pins D6, D7 and D8 on the device to control the strip, so I needed to change their modes to OUTPUT_ANALOG. By following the steps below you can see how I did that without any programming at all.
DeviceServerNodeMcu.ino is this the main program running on the device
The VoffCon control Card:
