I need to control 24 servos but I do not know how to do with I2C. I saw some componentes that do it with USB, but I need to do it with I2c.
I am working in a robot with 8 legs and 3 degree of freedom in each leg, so i need to connect and control 24 servos to any arduino board, could be possible with an arduino mega and a sensor shield like that show in https://arduino-info.wikispaces.com/SensorShield but I want to do it using two "16-channel servo drive" like this https://www.adafruit.com/product/1411, each of these can control 16 servos using only 2 pins from the board and it is “Chain-able” design so i could connect 2 of this to an Arduino Uno board or Raspberry but I do not know how to do. Any one can help me with I2C chains connections.
