The design is mainly achieved the network that based on the new short-distance wireless instead of the traditional wired as a family of internal data and control network, and built smart home managementsystem based on embedded GSM technology . The design of smart home managementsystem consists of five parts: ARM controller platform, mobile phones, GSM wireless communication module, Zigbee Coordinator nodes, Zigbee Terminal nodes and sensor parts.
Stepper motor is a common electromagnetic device, the corresponding circuit of control and driver, effective algorithm of acceleration and deceleration play a very important role in improving overall performance. Many advantages were achieved using the control system based on ATMEGA128, such as higher simplicity, low cost, high reliability, high torque at low speeds, and high motion accuracy. At the same time, by using algorithm of acceleration and deceleration, the efficiency of stepper motor is further enhanced, and the actual effect of control of stepper motor is smooth and has good results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
