p35 of the starter kit book states, when adding a push button to the project, "You'll also need to add a 10k-ohm resistor from ground...That pull-down resistor connects the pin...so it reads LOW..." Fine. It works. All is well. I removed the 10k-ohm resistor and replaced it with a 220-ohm resistor.…

10k- v 220-ohm resistor and a push button.
