WebThe pins can be configured to use built-in pull-up or pull-down resistors, except GPIO2 (board pin number 3) and GPIO3 (board pin number 5), which have fixed pull-up resistors. The GPIO pins output 3.3 V for logical HIGH and 0V for logical LOW. They read 3.3V as logical HIGH and 0V as logical LOW. WebThis leaves the input floating, which means that its value cannot be relied upon and it will drift between high and low depending on what it picks up in the way of electrical noise. If it is set to GPIO.PUD_UP, the pull-up resistor is enabled; if it is set to GPIO.PUD_DOWN, the pull-down resistor is enabled. WebJan 26, 2015 · The GPIO ports consist of software configurable internal pull up and pull down resistors. Pull up resistors have a value between 50KΩ ~ 65KΩ and pull down resistors between 50KΩ ~ 60KΩ. You should use following commands to configure it.
