I need to provide external power for the servos as I'm using a lot of them. Can any one suggest any voltage regulator for the external supply of voltage and how do I connect them to the servos. Does anyone have some images of the wiring that would guide me...
Which voltage regulators shall provide the juice for the servos? I have four servos in each arm of the robot. Shall I use one voltage regulator for each arm?
Here ya go , 4 - 5 volt regulators @ 5amp in parallel
This will give you up to 20 amps to power lots of servos! Most high torque servos draw 1-2 amps at stall and standard servos even less , maybe 200-500 ma per servo. If for some reason 20 amps is not enough ( not likely) you can add another regulator to the same setup. Be sure and make sure you use wiring with appropriate gauge to handle the current. This calls for 10-12 gauge stranded wire. Use a barrier strip and spade crimp on connectors to connect several servos to this regulated power source. This should resolve your servo power needs
That is really very useful... Thanks a lot Josh...
How about my third doubt regarding Lm1084.. Can I solve that issue?
The EZB v3 onboard PIC needs the 5 volt supply , you will want to have a good 5 volt regulator on the EZB V3 for the PIC digital pins to function properly. If the regulator went bad from overloading or other problem then -carefully- replace it.
So can I go for any 5v regulator that is compatible with the pins of LM1084... How abot LM1085? It gives 5v at 3A. I know that won't be sufficient to drive all the servos from EZ-B... So can I take the LM1085 to drive only components like HC SR-04, camera, MP3 Trigger from EZ-B and the rest of the servos from external power suppy...
The 3 amp regulator will work fine , just don't expect to power all your servos from the ezb , external power is the way to go for motors and servos because they are so unpredictable in their current draw.
Thank you Josh, for that quick replies... I would try that 3A regulator for EZ-B and add external power supply for the servos... I will try that today and get back to you...
Once again Thanks a lot Josh...
Your welcome!
Hey Josh,
I have an issue... I was trying to check if the digital pins has got anything to do with the LM1084... Using the Set Digital.. I tried to read the voltage out from Digital pins. I'm reading a 7v when it is SET. I'm using a 12v battery to power EZ-B. Does it mean that the components used on EZ-B would work even without that regulator LM1084 if we supply the external voltage to each of the components. What should be the ideal value on Digital pins when they are set?
@DJ , please guide me through this.
