Extremely easy to get going with this. I tinkered very lighlty with Arduino in the past and wanted an easy way to make REST requests and display data pulled down to external displays. If you are familiar with Linux command line and python this is a must-have. The Python GPIO module is easy to use and there are so many possibilities with this. I installed Rapsberry OS to get going and will probably stick with it. Very impressed with the pi, such a small device yet so much power. Will definitely get a four and install retro pi at some point
