Hi. can i ask you how to use stream video widget with OV7670? how is the connection for OV7670 and arduino? Thanks
Hello, I moved your PM into the public forum as it should be.
Connecting that camera to an Arduino and producing a streaming video is outside the scope of this Blynk related forum… but Google for that and you will find all the info you need.
Then, once you have a valid video stream… you simply enter that URL into the Video Widget and it should work.
