I'm building a temperature sensor where a fan operates when certain temperature limits are met. The question I have is about current on this project.
Im using a LM7805 volt reg which gives a range of 5mA to 1A. I'm trying to figure out how much current will be drawn when all my components are active. Im using the following with their typical current values:
PIC16F688: 95mA
Fan: 220mA
LCD: 3mA
DS1820: 1.5mA
Does this mean that a simple adding of these values give over all drawn current?
I need to know how much current will be drawn. I've read something about parallel current but I didn't really understand it...
