How To: Program a $6 NodeMCU to Detect Wi-Fi Jamming Attacks in the Arduino IDE

Hackers and makers are often grouped under the same label. While hackers draw on computer science skills to write programs and find bugs, makers use electrical engineering to create hardware prototypes from microprocessor boards like the Arduino. We'll exercise both sets of skills to program a $6 NodeMCU to display the status of a Wi-Fi link via an LED, allowing us to monitor for jamming attacks.
