Abstract: This design uses Atmel's 8-bit microcontroller AT89C2051 manufactured right car,
tracking, and robot control, through the I / O interface, the output signal as the control of stepper motors and buzzer signal, the signal sent by the part of the detection circuit into the microcontroller, and then drive a stepper motor running, driving car to run forward and backward, adjusting the car the way forward, and the driven machinery hand clutch and release, while controlling buzzer play voice. Part of the circuit mainly includes the following: tracking circuit, infrared detection circuit, power supply circuits, motor pros and cons of conversion to the circuit, the watchdog circuit. This design is a test, micro-control, such as technology integration, application number of electric, modular electricity, small systems design, technology design. The design can be applied to a number of very difficult operating environment, quickly and conveniently.
