There are three ways to use a pull-up or pull-down resistor with Arduino:Using an external pull-down resistor Using an external pull-up resistor Using an internal pull-up resistor (recommended)※ NOTE THAT: Arduino boards used ATmega AVR MCU (e.g Uno, Mega...) do not have the ...
So, in this case the calculation is(5.0V – 0.4V) / .003A = 1533Ω. That represents the lowest possible pullup resistor value, commonly designated RPyou can use, because anything less would burn out your I2C pins. The value of the resistor would be larger with a smaller IOL, so the...
