The materials that are required to make your own controller are shown in the following figure. Think about what you would like your controller to look like and how many buttons it should have, as this will determine how many of each item you will need:
The preceding figure shows the items we need to create a controller and the details are as follows:

We also need a safe way to connect the wires to the Raspberry Pi. One approach is to use special male to female wires, which behave like normal wires at one end, but can...
