hello all, i have make all in this link http://www.arduino.cc/en/Tutorial/ShiftOut but iam using ExtraOutputs.h libary, the problem is when the arduino power on it's make the ship 565 all on and off how to stop this i want no pin on when it's boot in ship 565 thanks
Use pin 13 the output enable. Connect this pin to a 10K resistor going to 5V. Also connect it to an arduino output pin. In the sketch in setup() have this pin go low. From that point on your outputs will be enabled.
thank you, but i do not want all pin on i want all off when it start what i must do
Also connect it to an arduino output pin. In the sketch in setup() have this pin go low
it’s = i connect it to ground?
You can set the levels at what ever you want them to be and they won't be active UNTIL you ground the output enable. A logic zero connects the pin to the ground a logic one connects it to 5v.
If the disabled output state is not what you want it to be then connect a pull up or pull down resistor as appropriate.
