1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[Details]
I. Introduction
Since RS232 has a short communication distance (only 15 meters according to EAT/TAI-232 standard), and can only perform point-to-point communication, it cannot directly f...[Details]
General LED lighting has a current limiting resistor in the driving circuit, and the power consumed by the resistor has nothing to do with the LED light emission. In order to improve efficiency, a...[Details]
