currently i am trying to build a robot comprising of
2 SPG30 60K dc geared motor with encoder which requires 12V, 410mA X2
SPG10-398k which requires 6v
arduino mega 2560
servo C40R which requires 6v maximum
IR sensors requiring 5V
now im confused how to arrange or plan my power source for all this... i have 4x 18650 battery...
and for each voltage regulator there is a limit of 1A, so i cant regulate the voltage in series(12v, and then regulate again with 6V, and then regulate again with 5V, all in series) because all the currents add up will exceed the 1A limit at the first 12V regulator righ?
does it means that i have to connect 4x 18650 in series, supplying power, then regulate it with 12V voltage regulator,
and then buy another 2x 18650, and then regulate the power to 6V, and next regulate it to 5V in series? so that i can power up arduino, servo, and IR sensors?
or i have to spend again to buy 12V LiPo battery to only use for the spg30e-60k?
