Internet Controlled Car

Abstract

An existing remote-controlled machine will be designed according to the following project plan: The control will be carried out via Wi-Fi, and the order will be made from a web page hosted by the ATmega164 microcontroller. The control of the engines of the car will be done using a DC- DC converter with the H-bridge. The power supply of the assembly will be realized with the help of 4 1.5 V AA batteries, connected in series. The Wi-Fi connection will be provided by an ESP-12F module that will allow the microcontroller access to the Internet network. The circuit will be designed on a printed wiring board, designed with the Eagle software, and the software development of the project will be carried out in the Atmel Studio environment. To control the direction of the car will be used two DC motors, the one in front for the left-right direction and the rear one for the front-rear steering. The front-engine is equipped with a mechanically driven mechanism, which will move after the engine is actuated and will move planetary for the left-right direction. The functions of the car, compared to the existing one that only could be controlled by the remote control, are the movement in the four cardinal points according to the orders received from the web page, as well as the illumination of the road by lighting the headlights in front. Also, on the web page, you can see in real-time the battery voltage level.
