HELP! How do I use the 16 channel PWM driver to add GPIO's!?

Other Hardware Sensors

Hi there! I am fairly new to using the Arduino platform and devices, so this might sound like a dumb question. I recently bought a PCA8596 16-Channel PWM Driver and it works fine. I know its intended purpose is to be used to place more servos on Arduino; however, I was wondering if you could also possibly use it to control DC motors or Sensors.

I have HC-SR04 ultra sonic sensor and a color sensor i want to add to my Arduino UNO but the problem is that i won't have any more pins. So, is there a way I could use the pwm driver to connect the color sensor and the ultrasonic sensor and how would you code for them?

You don't. You can set the outputs to 100% or 0% and have on and off but you cannot read the pin values.
