Paso 3: programación.
T1 = Pin 7 = E
T2 = Pin 8 = D
T3 = Pin 9 = C
T4 = Pin 10 = G
T5 = Pin 11 = F
T6 = Pin 12 = A
T7 = Pin13 = B
El T indica los números de transistor como en la página antes de o en la página después de éste. A, B, C, D, E, F, G son estandarizados segmento siete letras. Sobretodo he normalizado siete nombres de la letra del segmento para su referencia.
