How would you send data wirelessly from arduino uno to a pc?
I know you can connect wifi shield / wifi breakout to arduino and use that, but what other ways are there and how practical would they be?

You have several options. One is Bluetooth and another is nRF24L01+ 2.4GHz Wireless Transceiver. I love the
nRF24L01+. They are cheap and there are tons of examples online.
The concept with the
nRF24L01+ is to connect the RF24 to a Ft232rl Ftdi Usb to Ttl Serial Adapter. The Ft232rl connects to your PC. Most modern computer languages support communicating via Serial. This is the way to go.
Google around for a ton of tutorials
