Robot Building Questions

Virtual Programming

We would really like the ability to program a virtual JD robot so that we can preview the behaviours prior to connecting to the robot. This would enable a whole class to participate. While we can buy 10 robots, we cannot get enough to satisfy the 30+ kids working in pairs.

Ez-Bv4/2 3.3 Volt Digital Output Max Sink And Source Currents?

Looked around forum a bit and looked at the ez-bV4/2 data sheet but haven't found the max source and sink currents for the 3.3 volt digital output pins (each pin).
