Design of Remote Control Trolley Electrics Based on Wireless Module
Abstract: This design take designs topic request as a goal,using STC12C5A60S2/AD series single-chip as the core processor,combining motor-driven system,the car was controlled through the wireless remote like controlling the start and backlash,turning left and right and stop,which realize the car's location and function.The overall system electric circuit structure is simple and the realize performance is high,which can be taken for the model of the high-level intelligent toy and controls remotely the automobile.This design was combined with practice ,which has the practical significance and the very high market value.
