[BUG] The pin #7 should be inside list comprehension.

After code refactoring, the pin number related to the DP segment was left outside the list comprehension call, adding the **integer 7** instead of the **pin ard.pin[7]** object. This bug was not affecting the example because DP (pin 7) was not being used.
Unfortunately no. This list is ordered according the segments in the display, ordered as: A, B, C, D, E, F, G and DP (pin 7 in the Garoa Shield). This list is then unpacked during SevenSegments object instantiation, which DP segment is the last parameter (optional):

```python
seg_display = parts.led.SevenSegments(*display_pins)
```
