Step 6: Add the binary inputs

An easy way to do this is just to use some tiny jumper wires for this, so that you don't have them in your way when you insert other components.

Digital Pin 8 of the Arduino connected to: pin 1 of 4511 (Binary pin 2)

Digital Pin 9 of the Arduino connected to: pin 2 of 4511 (Binary pin 3)

Digital Pin 11 of the Arduino connected to: pin 6 of 4511 (Binary pin 4)

Digital Pin 12 of the Arduino connected to: pin 7 of 4511 (Binary pin 1)
