Arduino 03, digital signal read, with button 0 1
Hello to everyone in this video we see how one reads the digital data from the serial,
digital are called so xke may have only two types of values 1 and 0,
in this case the value 1 will be equal to the value 0 to 5v and 0v,
at this point we open the serial port, we note that the value is 0 0v, just press the button, the value changes to 1 that reads 5v
