I am using Arduino Mega 2560
I have built an structure with plastic 3D pieces to move this water tap.:
I am using the "Servomotor Parallax Inc 140 mA, 4 6 V" to rotate the tap:
Some more images to show how I mounted it:
Video 1. I tried to use the power of the arduino directly (5V). But the motor is not steady in all the positions I set, in some positions the noise you hear in the video do not stop, and my impression is that the motor will burn soon because it keeps pusshing all the time.
Video 2. Without almost any load, the motor is also making a small sound. I don't know if you can appreciate it in the video. They are like cracks or clicks
- Is there a way to cut the power supply when the motor already moved the tap? Or just to stop the motor to keep pushing?
- Using a external power should solve the problem? I found this tutorial where they use that system. Which will be the benefits of that? It will fix the problem?
- Using another stronger servomotor?
- A stepper motor?
- Is my servomotor faulty?
- Would I need some controller?
Any other suggestion?
