A ESP8266 script to rickroll people. Creates an AP with a different name every 5 seconds with strings specified (By default, lyrics of Rick Astley's Never Gonna Let You Down). Not necessarily for rickrolling as you can use it to advertise products or to do a PSA.
It took me 45 minutes to write this (15 if you leave out me trying to find out how to create an AP) Live blog-ish starts here and ends here.
