I'm not sure how many the UNO can handle natively but I use the Adafruit 16-Channel 12-bit PWM/Servo Shield - I2C interface which allows 16 servos. Using the shield allows the UNO to perform more functions without having to manage servos.

The UNO has 5 pins which are PWM capable. Pins 5,6,9.10 and 11, or you can use the board suggested above.

You use this chip with Arduino and B4X?

I need connect 8 servos, 3 sensors and 1 remote control IR.

So I bought a chip of these: generic PCA9685: U$ 2.0.

It will take 45 days to arrive.

The question is how control the servo motors using B4X and this chip and Arduino UNO?

Anyone have a diagram?

Some sample code?

Thank you.
