Yes. It's easiest if you can get some small electrical connectors found on the LED and switch connections on most modern computer cases, specifically 3 pin connectors (even better if they have wires already attached). These just slide onto the solid pins on the EduBot's motherboard, and, if you scrounged the connectors with attached wires, you can twist the bare wires together, and bind it with Scotch tape. Well, that's what I did, anyway.
The pinouts for the connections to the EduBot are documented and published in the EduBot documentation.

For the analog inputs, White is +5VDC, Red is the analog input, and Black is Ground.
For the digital inputs, you just short them together.
One problem I faced when connecting the provided optical sensors to the EduBot was the fact that they require 12VDC to operate. The battery pack on the EduBot only provides 5VDC through each individual analog input port. To circumvent this problem, I connected the Vin pin on the optical sensor to the positive terminal on the EduBot's battery pack. The battery only supplies 7.2VDC (perhaps it was 7.6VDC, I can't really remember), but it seemed to be enough to run the sensor. Perhaps popping a single 9V battery on the chassis of whatever you're doing would be a better idea than what I did, but oh well.
If you have any more questions, or need any clarifications, please feel free to ask.
