 | | Light Sensor question —Sam Kabra
|
| | | I'm new to mindstorms so I have a simple question. At work, we're trying to measure the light tightness of rings. Basically this involves observing how much light passes through the outside edge of a ring. Is there any way a mindstorm light sensor (...) (20 years ago, 8-Jul-04, to lugnet.robotics.rcx)

| | | | | (...) Sam, you need to tell us more about 'how much' light-tightness you want and if the ambient has some or no light at all. As an extreme example, in testing a photographic darkroom for light-tightness it is common to hang a few rolls of unexposed (...) (20 years ago, 9-Jul-04, to lugnet.robotics.rcx)

| | | | | | Basically there's enough light coming through that it would expose film quite quickly. Also, the ambient does have light in it. If the lego sensor isn't sensitive enough, could I easily replace it with another? (20 years ago, 14-Jul-04, to lugnet.robotics.rcx)

| | | | | | Thanks, I'm picking up my mindstorm kit today and if I run into any problems, I'll post another quesiton. (20 years ago, 15-Jul-04, to lugnet.robotics.rcx)

| | | | (...) Sam, By default programming when you configure a sensor input to be a light sensor, it gives you back readings in the 0-100 range (i.e. percentage of the maximum possible reading). To get better resolution (which I expect you might want), you (...) (20 years ago, 15-Jul-04, to lugnet.robotics.rcx)
