On the Subject of Shipping Triangles

No, this isn’t cargo.

Refer to Appendix 1PP1NG for identifying modules in the Triangles family.

This module will have 9 triangles on it. Each triangle is coloured red, green, or blue. To solve the module, press all valid triangles. Pressing an invalid triangle will cause a strike. Note that triangles turn off when pressed, regardless of validity.

Identifying valid triangles:

3 of the 9 triangles will flash the same letter in Morse (red), tap code (green) or Braille (blue).

Morse:

Tap Code:

12345
1ABCDE
2FGHIJ
3LMNOP
4QRSTU
5VWXYZ

Braille:

A cyan flash is used to indicate the end of sequence, instead of a long pause. All raised dots in the transmitted letter appear on the sequence as as many flashes as its position in Braille order, e.g. "C" would appear as [1 flash] [pause] [4 flashes] [end].
