Which side of an LED is ground? - Quora

NettetThe buttons are active low, meaning that the input will be connected to ground when the button is activated. The buttons have no external pull-up resistor, and therefore, to use the buttons, the P0.11, P0.12, P0.24, and P0.25 pins must be configured as input with an internal pull-up resistor.. The LEDs are active low, meaning that writing a logical zero … NettetConnecting the pin to ground with an internal pullup resistor means you use less parts.

The HDD LED/UID Switch connection is located on pins 13 and 14 of JF1. Attach a cable to. pin 14 to show hard drive activity status. Attach a cable to pin 13 to use UID switch. NettetThe LED’s legs are connected to two pins on the Arduino: ground and pin 13. The component between the LED and pin 13 is a resistor, which helps limit the current to prevent the LED from burning itself out. Without it, you’ll get a warning that the LED might burn out soon. It doesn’t matter whether the resistor comes before or after the ...
