 | | Drive a motor using the sensor port - safe? —Ka-On Lee
| | | | I accidentaly discovered that when the sensor port on the RCX is set to light sensor type, a motor connected to it will run. The motor can only run in one direction with a low torque, but it can be useful when you just need the extra motion and (...) (23 years ago, 18-Jul-01, to lugnet.robotics.rcx)

| | | | | Should be OK, the light sensor mode works by measuring the resistance of an external LDR (light-dependant resistor), so it is designed to cope with the equivalent short-circuit of a stalled motor.. the only problem might be the back-emf generated if (...)
