WebNov 18, 2015 · I used the following code to digital read the pin input and see if it is high or low. The problem is the Arduino is giving the wrong values. It gives some times 0 or some time high even though the pin in always low. It also gives low or 0 as answer though the pin is high is there any one able to help me with this? WebWhen we press the button, the value is always LOW, but when we release it it’s quite random: sometimes HIGH, sometimes LOW, and it moves a lot. We see this because the voltage for the button is floating between 0 and 5V. If the voltage is below a certain amount of V, the Arduino will read LOW.
