How? I have just completed my latest project which is a neon lamp which lights up every time someone visits my website. It’s controlled by a little relay board I built out on an Adafruit permaproto board and connected to a Raspberry Pi. The Raspberry Pi is running a simple python script which generates an event every time someone loads this page. I’ve made the part which integrates with the website open for anyone to use so you can build this out for yourself - have fun!
