WebThe key function of an ideal diode is to control the direction of current-flow. Current passing through a diode can only go in one direction, called the forward direction. Current trying to flow the reverse direction is blocked. They're like the one-way valve of electronics. WebDec 7, 2024 · When the output port is fixed at open-collector/drain state, then there is no additional equipment necessary for pulling down the pin’s output value. In this configuration, it turns off entire pull-up transistors and only drives pull-down transistors of the port pin when the latch pin of the port is in logic ‘0’ state.

WebDec 5, 2012 · The 'setup' function defines the ledPin as being an OUTPUT as normal, but now we have the two inputs to deal with.
