WebA pull is a physical connection of the pin to either the supply voltage ( 3.3V) or GND. This is done inside the microcontroller using a built-in resistor that connects the pin to the high or low voltage source. So, if you read the pin when no input signal is present, it will read the value of the pull direction: down = low and up = high. WebDescription. Read state of digital pin () block is a boolean block available in evive block, Arduino Uno block, Arduino Mega block, and Arduino Nano block. The block reads the state of the digital pin on evive (“High” or “Low”). If the state of the pin is “High”, it returns True, else False. Available pins in evive: 26 digital pins ...
