... 0,5 volt. Will the digital input pin register that?
Hello all What is the lower limit of voltage, the Arduino Uno will register on one of the digital pins?For example, a curcuit is connected trough Arduino 5V and GND and have a output at only 0,5 volt. Will the digital input pin register that?Thanks
So if I go below 3V on a digital pin, the Arduino Uno would not register it as HIGH.Thank you
Those values are best defined and explained in the Atmel ATmega329p datasheet along with all the other electrical specifications for the chip.Lefty
Well, I didn't "say" that, but you asked about "0.5V"In fact there's a point at which a voltage "must be" a HIGH and a similar point where some voltage "must be" a LOW, but there's a window of uncertainty between the two, a sort of no-man's land which should be avoided.
Unfortunately, that didn't help me
