Creating the Second Routing
The second routing is a little more complicated - it uses a resistor, and uses multiple jumpers to create a connect to both an IC pin and the input controller:
One thing to note in the circuit diagram: when crossing wires are connected, the diagram has a 'dot'. If they cross without a connection, there is no dot.
This routing requires inserting a resistor into the
breadboard (it is a '10K' resistor, which will have the brown-black-orange color combination). In this case, we go from the positive power rail, through the resistor, then into the second-right chip pin. We also then run a jump into an open spot of the breadboard - this is where our input controller will eventually be located:
It's always good to double-check your work after each two steps, so let's take the opportunity to verify that all our wiring is correct.
