The purpose of this paper is to design and implement the remote control lab using PDA (Personal Digital Assistant). This system integrates different fields of technology. They are Internet control, mobile control, and e-learning. We expend the e-learning to m-learning (mobile-learning). The wired control will become wireless control. Thus, the teaching will not be limited by time and location, and teaching resources and equipments can be integrated and shared, so the safety events can be monitored and handled in time. We provide an environment to train students to handle factory automation, data acquisition, data management, and manufacturing process using mobile devices. In addition, we also emphasize the integration and sharing of teaching equipments via internet and provide an environment which promotes learning interests and efficiency by using mobile devices via Internet.
