In this demo, we will be getting our hands dirty the Raspberry Pi and Nodejs. We will be writing a simple program in Node.js to turn a LED on and off. Then we will extend this logic to build a simple piece of embedded system that can take a piece of string and emit its morse code.    


  • 1 x Raspberry Pi (We used a Raspberry Pi 3 Model B for this demo)
  • 1 x Breadboard
  • 1 x 68 Ohms resistor
  • 1 x LED
  • 2 x Female to male wires
