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?

  • Almost everything else would require an additional adapter. – Ignacio Vazquez-Abrams Sep 12 '14 at 18:11
  • Laptops and smartphones come with built-in bluetooth, maybe use that? – zoran404 Sep 12 '14 at 18:15
  • You would need a bluetooth extension to the arduino this one would work over serial ebay.com/sch/…. Then you would need to do bluetooth programming on your laptop or smartphone. You can look this up for the specific system you are using. – Treesrule14 Sep 12 '14 at 18:23

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

  • Could you describe how you can plug the nRF24L01+ to a PC? This is what the OP wants to do. – jfpoilpret Sep 12 '14 at 18:56
