Controll Railway Model With Visuino Programmed ESP8266 Wi-Fi

The project is under construction.

The aim of the project is to achieve locomotive control via wifi with two ESP8266 modules.
The power supply of the locomotive is a 7.2 volt battery.

The new brushless motor is used to drive the old locomotive model.

Analog speed control is made with a potentiometer.

Turning on and off the lights and changing the direction of travel is done with the buttons.

From the locomotive we get the actual engine revolutions and the calculated distance traveled.

In addition, we receive an analogue battery voltage signal.

The motor control is via PWM 1 kHz. The best would be 3710 Hz.
The biggest problem was the simultaneous operation of two analog inputs.
