When I started working with Arduino, I purchased an assortment of 1/2W resistors. Now that I have a design nearly complete and starting to see there real power requirements, I can see that most cases my power is well under 1/8W. So I was wondering if I should be concerned about using resistors of a higher power value than required. Should I just use my 1/2W for everything or is there an advantage to getting a stock of 1/4 W and 1/8W and install them appropriately. Is there any margin of safety that should be maintained or some percentage range I should stay between.
