Based on the different controlling mode, we realize to control the curtain machine by mutual transformation of semiautomatic and automatic controlling and infrared remoter. This design is made up of infrared remote circuit, systematic controlling mode, electrical source transformation, protective circuit, etc. It can reach the achievement of automatically rising and falling of the curtain. Key words: SCM; timing control; photoelectric switch; stepping motor Abstract: According to the requirements of office and living environment,
