Arduino Uno
Do I need a shield or to be plugged into a computer? I want to run my arduino off a USB power pack and am wondering if I can still use Blynk. I just got the app, so sorry if I should know the answer.
You can connect over USB, but it’s not very easy for beginners and it involves software developed by other guys. Blynk initially was designed for a wireless connections, for the Internet of Things.
You can follow instructions here: http://docs.blynk.cc/#hardware-set-ups-arduino-over-usb-no-shield
If you have any issues with that - please write here, we’ll try to help. Also, search the forum for trouble shooting
Thanks, I will run it wireless
In the library there are examples for many types of supported shields. Choose the one you have.
