Hey guys,

I am going to be using a 6V battery for my project and need to step it down to other voltage for different components (i.e. 5V for arduino mega and my controller, 4.8V for servos, 3V for some other components). I am thinking of using a simple 2 resistor voltage divider since I dont know other ways minus a transformer. I know the basic equations (i.e Vout = (R2/R1+R2)Vin) but the thing I am stumped on is choosing the resistors. I know I can calculate the resistor values using the basic equations but I am not sure on if it will be better to use a combination of lower resistance resistors vs. higher resistance assume I can find a high reistance and low resistance pair that will do the same step down. Also, If I can find the right resistor pairs how do I choose the right wattage for the resistors as I have seen they typically come in 1/8, 1/4, 1/2, etc watt resistors. Thanks for any help also any suggestions on better ways to step down the voltage are greatly appreciated.

Just ran a quick calculation and wanted to throw in a example of the different resistor combos i.e. to step down 6V to 5V you could use R1=100 ohms R2=500 ohms or R1 = 1k R2 = 5k
