I am struggling with my new NodeMCU ESP8266. I like many kids saw this device on a YouTube video and wanted to prank some buddies with it, using it as a Wifi Jammer. I followed many tutorials and just when I finally thought I had finished, the thing stop working as I thought it would. It no longer transmitted a wifi network and the blue led would flash blue for a second when plugging it in then it would no longer turn on.
So my problem is that I don't entirely understand how to program the ESP8266. If someone could link me to a good video or article explaining extreme basics of this that would be great. Just for reference I am a second year in college (or university) studying computer science so I have an idea about basic coding.
Any help is appreciated. Thank you!
