It is not simple to setup the WiFiCar with the provided software. You should have good knowledge of network handling, and Arduino and C programming.
# Install the Arduino IDE (Integrated Development Environment) and the ESP8266 plugin Links #17 for programming the NodeMCU.
# With Arduino IDE upload my program wifi-car-AP.ino (Access Point mode) to the NodeMCU of the car.
# Power Up the NodeMCU, and try to find the WiFi hotspot (name: wifi-car) on IP address 192.168.4.1.
#Upload the provided JavaSript program wifi-carAP.js to the NodeMCU, via the URL http://192.168.4.1/upload (you will be asked for the File name/path).

== Shield Setup ==
* Motor power supply (VM): 4.5V ~ 36V, can be powered separately
* Nodemcu Control power (VIN): 4.5V ~ 9V (10VMAX), can be powered separately
* Logic Operating current Iss: ≤60mA (Vi = L), ≤22mA (Vi = H)
* Driver IC: L293, drive = PWM (Pulse Wide Modulation)
* Drive part of the work current Io: ≤1.2A
* Maximum power dissipation: 4W (T = 90 ℃)
* Control signal input level: High: 2.3V≤VIH≤VIN; Low: -0.3V≤VIL≤1.5V
* ESP12E Dev Kit Control Port:
* GPIO0: Motor DirA, Button FLASH; GPIO5: Motor PWMA
* GPIO2: Motor DirB; GPIO4: Motor PWMB
* The screw terminal is labeled with the signal names.
* The push button switch connects VIN to the board.
