I am using multiple tactile buttons. Each is using a pull down resistor of 10K, and a 100ohm resistor going to the digital pin. This is the most common, and acceptable, configuration I have seen. What I am unsure of is why is the 100ohm resistor is used when 5V and 100ohm will send 50mA to the digit…
