  • Led Matrix Pin 1 –> Arduino Pin A1
  • Led Matrix Pin 3 –> Arduino Pin 5
  • Led Matrix Pin 4 –> Arduino Pin 11
  • Led Matrix Pin 6 –> Arduino Pin A2
  • Led Matrix Pin 7 –> Arduino Pin 7
  • Led Matrix Pin 9 –> Arduino Pin 4
  • Led Matrix Pin 10 –> Arduino Pin 6
  • Led Matrix Pin 12 –> Arduino Pin A0
  • Led Matrix Pin 13 –> Arduino Pin 10
  • Led Matrix Pin 15 –> Arduino Pin 12
  • Led Matrix Pin 16 –> Arduino Pin A3
  • Led Matrix Pin 18 –> Arduino Pin 2
  • Led Matrix Pin 19 –> Arduino Pin 8
  • Led Matrix Pin 21 –> Arduino Pin 3
  • Led Matrix Pin 22 –> Arduino Pin 13
