Abstract：This paper introduced a kind of control system of cyclic light-emitting diode (LED). Stc15f2k60s2 was used as the
main control chip, and its timing and interruption system was used to control the output information, so that it can
adjust the brightness of LED and increase the performance of cyclic LED. Through the physical verification, this
design increased the cycle control of the brightness of the color lamp on the basis of the traditional cyclic LED
cycle on and off, and the combination of single on and off and gradually on and off on the basis of the cyclic LED
cycle state, which greatly improved the viewing performance of the color lamp. In addition, the powerful interrupt
system of the single-chip computer increased the storage and display of the alarm state and the cycle interval time
of the color lamp. It not only can improve the appreciation of the color lamp, but also expands the use scope of the
color lamp, greatly avoids the limitations of the use of the cyclic LED, and material resources.
