+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.
27 78
79
+- Install the Arduino IDE (Integrated Development Environment) and the ESP8266 plugin Links #17 for programming the NodeMCU.
80
+- With Arduino IDE upload my program wifi-car-AP.ino (Access Point mode) to the NodeMCU of the car.
81
+- Power Up the NodeMCU, and try to find the WiFi hotspot (name: wifi-car) on IP address 192.168.4.1.
82
+- 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).
83
+#With an Android Smartphone connect with WLAN to the WiFicar Hotspot (name: wifi-car).
84
+- Enter in your Web browser the URL http://192.168.4.1 . A HTML file is loaded (embedded in the C program) and the Java script file is loaded and executed.
85
+- As soon, as you tilt the smartphone, the WiFicar will move in that direction.
86
+- You should be able to see the interface similar to the right.
