I would like to make a robot powered by a raspberry pi. I would like to control this robot with my phone (on Android) and my computer using the local wifi network. I was wondering how to do it. I know how to control the gpios with a python code directy on the pi, but I think it's not applicable for remote control (I want to be able to modify the speed of the motors, turn on led, in real time). Can I do this in PHP, using the wiringPi library? Or is there another way?
