PCA9685 16-Channel 12-Bit PWM Servo Motor Driver with Arduino. 

Hi bro. Have you done the project? My servo not moving. If you done plz help me

@@susmitasarkar6955 I ended up using a blender plugin for moving servos. It’s for animatronics, check it out!

yes, but just make sure that your load is below what your power supply can handle

Theoretically you could put 6 servos on an Arduino Uno. But if you plan latter to add more, better go from the start with the PCA9685. Also, making all the pwm working correctly together at the same time could be hard. I never tried it, but I guess there is only one way to find out.

@@mylittleparody2277 Oh because PWM servo can't control servo together huh? and it can be done when we use this driver. Thanks for the explanation

@@AbdulRahman-jz3px Well, my bad. I was thinking about doing it by hand, using the timers to control the PWM, and thus limiting the max number of servos to the timer output pins. As it turns out, the official library allows to control 12 servos on an Arduino Uno (it disables the AnonlogOut()). www.arduino.cc/reference/en/libraries/servo/ So, the best solution for you would be to use the Arduino Lib. If you want to do it by hand, you need to set the timer to the first angle, and when the interrupt fires, set low the first servo's pin state, set high the pin for the second servo, reload the timer with the second servo, and wait for it to fire. doing so and switching servos in a round manner would allow you to control multiple servos with one timer. But it's probably easier to use the lib if you are not tied to bare metal.

im a bginner myself i just bought 20 servos for a human robot project i use a portable charger i bought from walmart as my power supple and it works very well !

u have to add servomotor driver in arduino id

@@yahmedbacc8265 and how do you do that
