I have a problem and it's urgent. I am not able to use the i2c LCD screen along with my servo motor in my project. I don't think so the servo motor is receiving enough voltage as both the LCD and Servo motor use 5V. So can I connect the signal pin of my servo motor with the 1st Arduino and the GND and VCC of the servo to the 2nd Arduino? Please help me try to solve my problem.
Thank you
Perhaps the problem is that a Uno is not a motor power supply.
A posted image and schematic would be prudent.
Yeah sure.
A Uno is not a motor power supply.
Servo stuff
Power externally.
A breadboard is not a proper power distribution block for motor currents.
power distribution blocks.
ok..but why not use a second arduino.. i mean if i connect a second battery to it??
I only have one servo motor
A uno is not a power supply for motors.
but when i used my servo motor seperately with the 5v pin of the arduino, it was working perfectly. i am using a 9V battery
but its not working when i use the LCD with it
Good luck.
The search box is a useful tool.
For instance, using the words such as "9v battery" in the search box one could find lots of reasons why this may be a bad idea.
Other search words include "level shifter", "round", "millis()", "move servos in increments"
oh ok
so you mean i should use 4 AAA batteries? and use the arduino 5v supply for the LCD screen? mine is a sg90 basic servo motor..
That's one way to do the thing. Another is to get a proper power supply for the motor. That motor, servo, needs at least 800mA available, far more than the Uno can supply.
Using this thing
you can find out how others have done the thing.
Me I build servo power supply boards.
Remember, connect the grounds.
hmm so basically any motor requires that much current..? even sg90.. i thought mine was too small so it didnt that much supply. There are many videos in the internet where they do use the arduino supply with sg90 right?
I did not write such.
Please feel free to follow your own path.
But did you use this thing
and words like "9v battery" in the search box one could find lots of reasons why this may be a bad idea? Don't take my word for it, use your current experience and the experience of others to make up your own mind as to why using a 9V battery is a bad idea.
i mean any servo motor, sorry..
