I bought three of these servos and found out I couldn't power it well enough with the Arduino. I looked into this servo further to see if I could find a datasheet, but only found store pages. Most of the pages state these servos run from 4.8V-7.2V, like this page.
I have a 12V LiPo battery I can work with, but would like to step that down to around 7V. I have no knowledge of zener or schottky diodes, but have been reading into possibly using them. Can someone help me understand how to use these type of diodes to safely step down this voltage?
I plan on having that 12V battery power 4 DC motors, as well as four servos for a robotic arm.
