the higher the value of the resistor, the less power it needs to dissipate.
You could use 'any old resistor' in a drawer for the job assuming that its acceptable in the circuit (since the resistor will end up being the top half of a voltage divider).
Traditionally in 5V microcontrollers, you use 1k or 10k or 100k depending on your mood/needs/circuit/persuasion. Due to higher voltages and current, you need to go higher to allow the resistor to have to dissipate less heat... like in say things like a guitar pedal, where you would often see 1.2M etc etc used on inputs to prevent 'popping' as it turns on/off...
Anyway.. nutshell - its a value thats a compromise and you can use anything that would otherwise work within the circuit/power constraints but ultimately its a tradeoff in so far as lower values need to burn off higher power values.... and also consume more power etc etc...
And no, I'm not that Adrian
