I know there’s a way to control Sphero using Sparkfun Bluemate with Arduino: https://www.youtube.com/watch?v=sqgj1ArspKw
So there’s got to be a way to control Sphero with Blynk right?
I’m a newbie though and not sure where to start.
Start by learning all you can about Blynk and how it works… that part we can eventually assist with as you go… a little Arduino experience will probably be necessary as well
Possibly then you can figure out how to merge the authors existing Arduino-Sphero-Library code, with Blynk as a control interface.
From that nausea inducing video, it looks like Sphero is using the a BT link, so you will not be able to link the Arduino and Blynk that way, thus you will need to either test your combined code on an ESP8266 or use an ESP as shield for the Blynk interface.
