Frequently asked questions
What current does 1.8kOhm give for an LED at 5V?
With a red LED at about 2V forward voltage, (5V - 2V) / 1.8kOhm is roughly 1.7 mA, which suits a dim indicator.
Is 1.8kOhm suitable as an I2C pull-up?
It works on short buses, but it is lower than the usual 4.7kOhm to 10kOhm range, so it draws more current when the line is pulled low and may exceed what some devices can sink.
