External power supply for Arduino project Answered
Hi all, I'm encountering issues while attempting to supply power to 6 servos, attached to an Arduino Due via a sensor shield. The servo model is Hitec HS-8370th, with 6.0 V to 7.4 V as voltage request; I'm trying to power separately the Arduino and the servos (as prompted by the whole onlne community) but I still can't find the proper combination of wiring and components. Arduino needs to be always connected to my laptop for transferring data to Python, so I thought I could simply use USB supply for powering the board; on the other hand, voltage and current requests by servos (joined with common sense) suggest the use of some external battery.
What kind of battery should I pick?
Moreover, should I put a capacitor (I found this rule of thumb: 100 microF per servo to guarantee current stability; so I bought a 1000 microF capacitor) between the supply and the servos?
Thank you in advance
