The Automatic Lamp<br />
You are going to program a lamp to turn on at night and turn off in the<br />
morning. Using the Investigator software, you can track the light data,<br />
view the results, and write a description of what happened.<br />
Attach the light sensor to the house model so that the sensor can see the light<br />
in the room.Add a lamp inside or outside the house — where you think a light<br />
sensor-controlled lamp would be the most useful.<br />
Make sure the light sensor is attached to port 1 and the lamp is attached to<br />
port A.<br />
Load the ROBOLAB software. Select Investigator.<br />

Using this level, you can set the RCX to capture or log data from two sensors<br />
and to program two outputs.The outputs stop after an event occurs.This<br />
program captures or logs the data from the light sensor and turns off the<br />
lamp when the light sensor sees a brighter light.
