WebDec 22, 2024 · The AD converter divides the target voltage into several equal parts. For Arduino Uno, voltages can be read in the range of 0-5V. These 0-5V values are divided into 1023 equal parts. The AD converter converts the analog voltage reading to the nearest equal value. If the voltage is 3V, for example, “614” is the closest value. 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.
