WiFi RC Smart Car based on ESP-12E

contact us to free get the Android APP source code.



This WiFi RC smart car is designed and developed based on ESP-12E from ESP8266, which can be controlled by mobile, PC, and wechat (now just in China). All of thedocuments can be downloaded for the DOIT official site:, including the scheme for car.

After get it, can further develop based on the Lua IDE.

Contact the service, can free get the Android APP source code. 

As for this WiFi car kit, it can work at many modes, such as: AP mode and STA mode.

AP mode:



STA mode:



Under the STA mode, the Doit Car can be controlled by phone APP, WeChat, and page frominternet. Note that, if using STA mode, you should firstly download the Doit Car Control.lua into the Doit Car. For more details about download methods, please visit thedocuments on NodeMCU development (). Before download the Doit Car Control.lua into the control-board, you must let the SSID name and password in Doit Car Control.lua same as the ones in your router. In addition, in the Doit Car Control.lua, you should rename the car as the one you like (the defaultname is car). This name is used as the device name controlled by mobile phone,Wechat, and web-page.

Thefollowing Figure is shown that car is controlled by web-page.


  • A novel design has already coming for the tank chassis, with beautiful shape, and full metal aluminum alloy structure. In this tank chassis, a space for 9g servo is left for the ultrasonic sensor, and a space for MG995 servo is also left to rotate the mechanical manipulator. What’smore, UNO R3 and NodeMCU development boards are also designed to install. In addition, the metal panel can be used to install the wheeled car by install the 25mm and/or 37mm motor frames. Interesting, a LED light is installed to brighten the dark in the night. Under the help of the motor, the tank chassis can be smoothly turn left, right, circle, forward and backward, ect. Therefore, when you get the chassis, it can do many things for you, like getting the temperature and mobile monitor. Certainly, we have developed a series of car/tank chassis. Hoping you can choose your loved car chassis.
