[vc_row][vc_column width=”1/1″][vc_column_text]In this tutorial, we will look at a special type of segment LED, which can be used to indicate the distance.
There are 8 pins of this segment LED:
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 the current, otherwise, the LED will be damaged.
The following are the tests we did (the current is 30mA):
First Segment (green)
Second segment (green)
Third segment (green)
Fourth segment (Orange)
Fifth segment (Orange)
Segment 6 (Red)
Seventh Segment (Red)
