Abstract: A resistive feedback network is often used to set the output voltage of a power supply. A mechanical potentiometer (pot)conveniently solve...
The MAX9257/MAX9258 programmable serializer/deserializer (SerDes) devices transfer both video data and control signals over the same twisted-pair ca...
为提高太阳能的利用率,以ATmega8单片机为控制核心,设计了一套光电跟踪与视日运动轨迹跟踪互补控制的双轴太阳跟踪器。该跟踪器在晴天时,利用光敏电阻采集光强判断太阳位置,控制步进电机实现光电跟踪;在阴天时,采集时钟器件PCF8583的时间信息,计算当前太阳位置来实现视日运动轨迹跟踪。实验表明:该太阳...
