Sometimes, it’s nice to feel like a Hollywood hacker and flex your superpowers! With this project, we will see how to detect if there’s a non-secure wifi around us. This is also handy when you travel and don’t have your usual places to connect to the Internet. You could be walking down the street until the GrovePi+ finds a coffee place or a restaurant that offers free WiFi. This is often referred to as ‘wardriving’
With Great Powers Comes Great Responsibility!
Knowing where there are open wifi networks is fine. Using those open networks for your own needs is most likely NOT fine, and may even be illegal. Better safe than sorry. Gain the knowledge but don’t use it unless given explicit permission by the wifi owner.
