Connecting a HC-SR04 (or Servo) to A0 ESP

Other Hardware Sensors
1

I connected 9 servos to the GPIO ( GPIO 0-8) of my ESP and now, basically, I'm running out of pins. I want to use the Analog Pin A0 to connect a HC-SR04 (using NewPin library) or a Servo motor. I have tried both without results, Someone knows if it is even possible?

PD: I'm using a ESP-12E motor shield that can supply my servos with 5V

Not possible. A0 is analog input only on ESP8266.

I suggest you get a PCA9685 to drive your servos. This will free up some pins for other uses.
