Raspberry Pi] 1. My new toy.

A few days ago I bought a new toy. It is Raspberry Pi 3 Model B+. I needed a small computer for testing and I was looking for this one and buying it. What can I do with this? I pondered. But could not find the answer. So first, I just installed the operating system using the Ubuntu 18.04.2 preinstalled server image file. Oh ~ what? I felt the something signal in my head is detected.

There was not an internal temperature sensor. I need something. a temperature sensor and other parts as well.

I feel it is going to be a fun toy. :D
