When you have your chip soldere, you need to put code ino your chip, and use it to control the project you made. The arduino is a easy and good software to do it.
Use these small things to be your input and output, usually put output at digital pin and output at analog in.
When you find some interesting input of output, but you don't know how to use it, maybe you can go to this website, and search for it.https://www.arduino.cc/
