Extend sensor input

hi
i have a 3pi but i want to use external sensors as per requirement of a line following competition, so how can i turn of existing senors output and put my own sensor pins , the sensors are quite similar to what used in 3pi just different voltage range.

so are the pins accessible ?

Hello.

You are not providing enough information for someone to help you without asking a lot of questions. Can you please describe your problem more specifically in your next post?

Here are some questions to get you started, but please provide any other details you know:

How many IO pins do you need? The 3pi has up to 5 user-IO pins, but not all the pins have the same functionality. From the specifications tab of the 3pi product page:

What voltage range do your sensors use?
