Telepresence robot with skype live stream?

Need Help With My Project
,
1

So im trying to make a telepresence robot like ive seen on you tube. Ive copied code that wouldn’t compile and tweaked it to do atleast that but im stuck on the part were i connect a skype video stream from the android phone on the robot to the live video widget on the app. Would greatly appreciate any help i can get as this is my first attempt at connecting anything to wifi let alone video streams. Im making a tracked robot with a wemos mini D1 connected to a l298n. The app uses a joystick to control it but i cant figure out what pins i should connect the joystick to in the app (virtual/digital???) New to this app and hope im posting this right because it isn’t the most intuitive. This code as i said was codied and reworked to compile but im not sure.

Simply paste your code between ``` If you don’t format your code, your topic can be deleted by moderators.
