The circuitry is formed around a microchip pic 16F877a microcontroller and programmed in CCS C language.
The microcontroller drives the motors via a generic L297 motor controller module
and controls the mp3 player module to generate sound effects, engine sounds and warning announcements. The proteus simulation file can talk to a mp3 module connected to the PC via a usb-TTL seral port converter. Therefore can play actual sound effect while being simulated on the PC.
The circuit can recognize IR remote control signals with the NEC protocol therefore the car can be cotrolled by a tv remote.
Various motor driver boards such as the L298 or BTS960 below can be used in the project. The firmware supports both of them. Others can also be adopted.
