To prevent this unknown state, a pull-up or pull-down resistor will insure that the pin is in either a high or low state, while also using a low amount of current. Pull-ups are more common than pull-downs.pull-up resistor is connected to the high voltage (this is usual.. 더보기 이전 1 ··· 33 34 35 36 37 38 39 ··· 168 다음
