This circuit is quite useful for displaying the states of digital lines. The two 330R resistors may need to be changed as the circuit I generally use is using a tri-colour LED(3 legs) with common cathode. Other LED’s may need more or less current.
| Input | Output |
| 0 | Green |
| 1 | Red |
| Nothing | No LED |
