how do i have no voltage output on digital pins

is it possable to have a digital pin to put out no electricity???
if so, how? :smiley:

A digital pin must be defined with the pinmode command to be either a digital input pin or a digital output pin. If the the pin is defined as a output pin it can take on either a 0vdc or 5vdc voltage state. If it’s defined as a input pin it will be just a very high impedance ‘floating’ pin and will not read out as a specific voltage level. Upon reset the default for pins is to be input pins.
