Finalizing our hardware setup
Now that we have a working scrolling message on our Pi Zero, we need to look a little more at the hardware and how we will use this as a badge we can wear on our clothes. The first thing you will probably be thinking is that the two bare circuit boards of the Pi Zero, and the Scroll pHAT HD with all their cables between them do not make the best badge you have ever seen! But fear not, as this section of the project will get everything looking far neater and ready to go as a badge.
Wiring an off switch to our Pi Zero
We are going to solder two more pieces of hardware to our Pi Zero, which we will program to act as an off switch for our Pi Zero. This way, if we are using our Pi Zero out and about, we will not need a SSH connection to it to ensure we shut it down correctly.
I am going to use a push button switch from Kitronix for my button, but you could use any type push button. The one I have chosen is designed for eTextiles projects and comes presoldered to it...
