Stream video from camera to mobile and send control signal back from mobile to Arduino via WiFi I want to make an Ardunio based project in which I want to stream live video from camera (which is connected to Arduino borad ) to my Android app via WiFi and send back actions/control signals from my android app to Arduino to controller servo motor which are connected to Arduino board. Right now I only have Arduino mega with me. What else components are going to be required?
You need good MPU with enough buffer size and nand size for such an intense process 

Search esp modules 

Thanks.
