HRK Posted September 2, 2019 Report Share Posted September 2, 2019 Hi,all I want to light the LED when the switch is turned on (for launch control and flat shift)The digital input is set to pull-up (12+), and the LED is going to be installed between the switch connected to GND.Is there a problem with power consumption?LED power consumption is 2.2V 20mAI'm going to drop the current with a current regulatve diode. Thanks. Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 2, 2019 Report Share Posted September 2, 2019 I dont think the internal pull-up will be strong enough. My recollection is they are 4K7 to a regulated 12V supply. Quote Link to comment Share on other sites More sharing options...
