It’s a good little microcontroller with lots of accessories, project ideas, and free code available. The programming software is easy to use. The Uno processor is not very powerful, but there are newer model Arduinos with more capabilities that use the same programming software and many of the same accessories. What do you want to do with it?

I’m going to build a FM radio for my dad with one as a pet project (overkill I know, but for fun)
But I interface with encoders, transducers (I noticed some pwm inputs) and mainly digital output to relays. I rarely have to use two or three channels of analog output.
I have experience in C.
I think the Uno would be perfect for that. Although you can build an FM radio without a microcontroller, using one gives you the ability to have station memories, a sleep timer, and other nice features. You can even get a real-time clock add-on and make it into a full clock-radio. I hope it goes well!
