Abstract
The paper presents a method for achieving constant illumination control by integrating various technologies, including Arduino technology, LED driver technology, and control technology. The HV9910B constant current drive chip is used to design a high-power LED driver in the form of an Arduino expansion board. The performance of the driver is tested, including efficiency testing and waveform testing. The PID control library of Arduino is utilized to write the control program rapidly. Illumination control experiments are conducted with expected results.
