Ever hear of a thing called RGB? Red, Green, Blue? How about an RGB LED? These 5mm units have four pins - Cathode is the longest pin. One for each color and a common cathode. Use this one LED for three status indicators or pulse width modulate all...

This is a special type of LED that has an RED arrow pointing. The rated voltage is 9A, and current is 20mA.   Schematics:

This is a type of LED used to form a dotted line. There are 5 segments, and each segment has two pins, and it has a total of 10 pins. It's pretty straightforwar to use it. Please make sure to use a current limit resistor to limit the current, otherwise...

This is a LED used to indicate the level of battery.  The are a total of 6 segment. One of the segment is the outer frame. There are 5 segments inside the frame that can be used to indicate the level of charge of battery.  There are a 8 pins...

This is a LED used to indicate the distance.  There are 7 segments on this LED.  All 7 segments share the same anode. The other 7 pins correspond to the cathode of each segment.   Please use a current limit resistor to limit...
