| (...) You are doing well Mark. You can use three voltage comparators to detect which voltage level is being output. What you need is three comparators. One for 25%, then 50%, and 75%. If 75% is on, then you'll need to gate off the 25% and 50% (...) (21 years ago, 15-Jun-03, to lugnet.technic, lugnet.robotics)

| (...) I was thinking that one could just use an ADC to directly convert the analog voltage level to a digital number of however many bits you could resolve it to and then taking that binary number to address a demux and have the demux's outputs (...)

| (...) When using LEGO's firmware and NQC the maximum number of power levels you have is 8 (plus off?), so the most you can identiy is 9. This of course presumes that current draw by your compressor's motors doesn't mess with the voltage going into (...) (21 years ago, 16-Jun-03, to lugnet.technic, lugnet.robotics)

| (...) Yes, the switches would need to remember their last set state. Ideally, this would be done through the use of electric pneumatic switches which, when not receiving any power, simply stay in the last position they were set in. If this isn't (...)
