My Raspberry Pi has turned into a central hub for automation and connections to various devices at home. As I want to expose some services outside of the local LAN, I run into the risk of being hacked. So what can we do to secure the Raspberry Pi from intruders?
In two previous posts, I used the RCSwitch and pi-switch libraries for communication between an Arduino Uno and a Raspberry Pi. I touched briefly on the main purpose with these libraries – to control RC outlets. In this post I will dig deeper and decode the RC signals so that the remote control can be replaced by a web app running on any browser-enabled device.
