(...) I'm doing somthing similair at the moment. My robot runs along a track and needs to be controlled so it doesn't go too fast.

Hello Iain, (...) You should definitely try Dick Swan's 10x firmware ((URL) Among other goodies (interpretation speed for example ;o), it features more power levels (128 instead of 8), and a flag to modify behavior of PWM motor control. Standard (...) (20 years ago, 30-Nov-04, to lugnet.robotics.rcx.nqc)

Hi, I'm trying to do a basic test setup to code a compact speed control module for the 9V gearmotor. I've mounted an encoder (rotation sensor) directly to the gearmotor shaft. In my code, I'd like to set a variable (speedDesired) and have the motor (...) (20 years ago, 30-Nov-04, to lugnet.robotics.rcx.nqc)

Hi, I was wondering if anyone has any experience programming (NQC) a stationary |light seeking head? I have one made using a rotation sensor for reference, and 2 light sensors but can't seem to get the programming down. |Thanks |John Jordan (20 years ago, 25-Nov-04, to lugnet.robotics.rcx.nqc)

(...) Not exactly. What NQC allows you to do is set one of 8 patterns of pulse width modulation (PWM) for an output. So for instance the highest power level is "always on" (9V for 100% of a cycle), while a lower power setting is a mixture of "on" & (...) (20 years ago, 7-Nov-04, to lugnet.robotics.rcx.nqc)
