Title: Resistors?
Post by: xCyclone on May 17, 2009, 07:56:06 AM

I am building the 50 dollar robot and I bought some resistors from Radio Shack. I needed 1.62 Kohm and a 340 ohm, but they only had 1.5 Kohm and 330 ohm. Would that make much of a difference ???

I found out more about the 330 via SoR fourm but... I still need help about the 1.62Kohm vs. 1.5Kohm

depending on the tolerance band of the 1.62 the 1.5 should be fine.

its most likely a + or - 10% (silver band)

1.62 x 10% = 0.162
1.62 - 0.162 = 1.458

measure ur 1.5's and pick the one with the highest value.
