(...) It's basically the same serial data connection as the RCX. It just uses radio for transmission instead of infrared, so it goes around corners and has a longer range. Jürgen (25 years ago, 3-Nov-00, to lugnet.robotics)

In NQC you count by adding 1 to a variable like this: int counter; counter += 1 But it's hard to know *how much* you have counted; however, you can build a little program to (say) flash a light when you reach a certain count. I have spent about 4 (...) (25 years ago, 2-Nov-00, to lugnet.robotics)
