IoT Projects with Raspberry Pi, Arduino, ESP8266 and ESP32
November 21, 2020
Internet of Things (IoT) is now everywhere. The rise of open hardware such as Arduino has triggered this phenomena and driven even further. The result is there are many interesting projects spanning various domains. Here we highlight some open source projects, in particular those which can be referenced for our own DIY (Do-It-Yourself) projects.

Learning introductory SDN concept with Mininet is mostly enough. But sometimes it is nice to have a mobile, small-scale SDN lab for showcase and live demo sessions in the class. Below you'll find a short guide to 'convert' a raspberry pi (RPI2) to a 4-port OpenFlow Open vSwitch. For this purpose, you'll need 4x USB-to-RJ45 adapter.

RTL-SDR is a very cheap software defined radio that uses a DVB-T TV tuner dongle based on the RTL2832U chipset. The RTL-SDR is also often referred to as RTL2832U, DVB-T SDR, RTL dongle or the '$20 Software Defined Radio'. There are many other software defined radios better than the RTL-SDR, but they all come at a higher price.
