Thereis neutral wire, which is at ground potential, and live wire, which has AC voltage. Some devices are double insulated so they can use 2 pins safely. Some devices are not and they need 3 pins for safety. 2 pin devices can be connected to either socket, but it will be unsafe to connect 3 pin devices to 2 pin socket without ground. Share.
DuemilanovePin 13 LED Uno Rev 3 Pin 13 LED (marked "L") LED: 13. There is a built-in LED connected to digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off. On recent official Arduino products (Uno, Leonardo ) it looks like the pin 13 LED is isolated by an op-amp buffer so the LED shouldn't affect use
brown274 I will be ordering some JH-13 V2 this week for portable player use only. These will be used for exercising and just listening to music through my portable players. I see they now have 4 and 7 pin cables (My old set has just 2 pin cables). Is there an advantage to either one? Is one geared more towards on-stage hookups or
Ahuge problem is PIN guessing from birthdays (dd/mm/yy lends to a 6 digit number that is easily guessed, dd/mm/yyyy for 8 digits). It's very often that a PIN number is taken from someone's birthday or year, either their own or relatives. There was even a case where a speaker had cracked the phone code of an audience live on-stage.. An odd

Yes not all 15 pins are required for a VGA connection. If your VGA cable/port is missing a pin, it is still possible for the cable to work. However, whether the cable works or not depends on which pin is missing. As discussed earlier, 5 VGA pins have become redundant and are not required for a stable display connection.
