Encoder - Which Type of Output ?


I would like to order an incremental encoder to my project of inverted pendulum. And there is a question I have to You: Is better to order an encoder with pushpull output or with open collector output to this project ?


You don't give enough information to proevide a definitive answer but you might consider the following:

In a push-pull sensor the "high' output will be approximately the power to the sensor. If this is 5V and you have a 3.3v Arduino you will have to do some level shifting.

With open collector you could use the internal pull-up of the controller or at worst a few resistors.

Good luck
