A Design of Voice Controlled Toy Car Based on SPCE061A MCU
Abstract: Intelligent and automation technology in the toy manufacture have been paid more and more attention in recent years. A design of voice controlled toy car based on SPCE061A MCU (Micro Control Unit) is introduced in this paper. The design and implementation of its hardware subsystem is mainly discussed. Firstly, The SPCE061A's main characters and pins function are introduced. Then design the modulation circuits, such as the power circuit, the reset, the keyboard, the audio input, the audio output, the wireless control circuit and so on. Finally, more detailed explanation to the process of producing and debugging is given. The debugging indicates that, if the background noise is not too big, and the master's pronunciation is clear, this voice controlled car can make the responses to the specific voice commands, finish the commanded movements.
