I've just started working with the Arduino UNO SMD edition and I'm also quiet new to electronics in general. Recently I wanted to try out this tutorial https://www.arduino.cc/en/Tutorial/Button and I ran into a problem with the pull-down resistor. In the tutorial they recommend a 10kOhm resistor but I've got only 460Ohms laying around. Obviously I could link dozens of them in series but I was wondering if it is possible to replace this 10k resistor with 460 Ohms. Would that be enough? I'm assuming, that the 5V Output can supply up to 500mA (datasheet) and the ground can take up to 500mA. Following Ohms Law I = U/R given 460Ohms there should be a current of 11mA flowing. Is it correct that the ground can take this amount of current?
Hope you can answer my question and may point out mistakes i made.
