Hi
I have a very estrange problem
servos are over heating the my arduino Mega.
any idea how to fix this
thank you
Don't drive the servos directly from an arduino pin?
Don't power the servos directly from the arduino 5V or Vin pin?
You really need to give us more to work from.
Ah, just saw the circle.
Suggestion #2 then.
thanks
I have the Adafrui motorshield Adafruit Motor/Stepper/Servo Shield for Arduino kit [v1.2] : ID 81 : $19.50 : Adafruit Industries, Unique & fun DIY electronics and kits
servos are running on pin 9 and 10
what ever I do they make the arduino over heat.
the same happnes with out the shield
Where are the servos getting their power from?
thankx
arduino is powering from 5v.
I just notice that I can add external power to the shield
do you know how to make a 5 volts regulated supply.
I have a 9 volts adaptor when I tested with multimiter reads 12 volts
9/12V to 7805 input pin, output pin to shield.
10uF cap from 7805 input to ground, 10uF from 7805 output to ground.
thanks CrossRoads
I was thinking to use this
CrossRoads:
9/12V to 7805 input pin, output pin to shield.
10uF cap from 7805 input to ground, 10uF from 7805 output to ground.
How is this setup.?
thsnks
so much.
you are a great help in the forums.
I only have 2 types of cap ( radioshack in my area only sell this 2 types )
100uf 6.3v
220uf 6.3
will this do the work
or should I change the wall adaptor for another voltage
I do what I can 8)
Put two 100's in series across the input so you don't exceed their voltage rating, put one 100 on the output.
You can put a small diode in series with the regulating chip ground (like below) which will up the output voltage to ~5.7v for better servo performance.
CrossRoads:
9/12V to 7805 input pin, output pin to shield.
10uF cap from 7805 input to ground, 10uF from 7805 output to ground.
I travel several miles to a radioshack that has this parts
I will try it soon.
thax
I thought that shield had its own power connector?
it does.
I tried it. and did suggested modifications on the shield , and unfourtunally the problem was not fix
the solution propose by CrossRoads ( witch is cheaper than the shield)
works better in this case
did you remove the jumper form the shield, it is located right near the external power input. Just dug mine out and saw that.
thanks you
sorry check my above post again as I accidentally edited it instead of posting down here. Fail on my part lol
indeed I did ,
a spend a lot of time at the net doing research on the problem
try every possible solution.
maybe my implementation creates this kind of problem
any way crossroads solutions works well for me.
