ya. i thought of using only 2 of available 3 cells. My battery totally has 4 terminals(one common ground, 3.7v , 7.4v and 11.1v) .. so, two cells will do the work. correct?
- - - Updated - - -
each cell will provide 3.7V .. 3.7*2 = 7.4 V ... will that not be enough for the 7805?
okay, we'll take the worst case. consider all my motors are in need of 500 mA, then the total current needed would be 500mA*10=5000 mA=5A . LM2596 can out only 3A of current at max.
I think using dedicated 7805 for each motor will not take out more power loss if use 7.4 V as the input voltage to...
I'm giving my servo's specs here
current drain - 8 mA (idle)
160 mA (no load work)
stall current - 600 mA
operating voltage - 4.8 to 6 V
I'm using 10 servo motor for my robotic leg, which will be controlled by arduino. I tried using a common 7805 for all the 10 servos...
