PAGE 24 Teacher Notes for use with Set 9795 SECTION 3 GETTING STARTED ACTIVITIES The Automatic Garage Door Learning Objectives Students will: Create an “electric eye” using the light sensor and a lamp that can be used to activate the garage motor. Write a program that runs continuously. Discussion The solution shown here is set for Continuous Run.The program includes a step in the beginning that turns on Lamp C (across from the light sensor) for half a second.This prevents the light sensor from being triggered at the start of the program and starting the garage motor too soon. Note: Since the program is set for Continuous Run, users must press Run to stop the program. 1 2 3 4 5 ACTIVITY 5

Build the door lock system as shown on pages 27-32 in the building booklet. Make sure the light sensor is attached to port 2, the lamp is attached to port A and the motor to port B. Load ROBOLAB and select Pilot 3. Using the View feature of the RCX, find the light sensor value range for each of the LEGO tile “key cards” built for the door lock system. To do that, create a Pilot test program that activates the light sensor in port 2. Download the test program and run it. On the RCX, select View for port 2. Place each of the LEGO key cards in front of the light sensor and record the values. Write the light sensor values here. White Red Blue Grey Go back to the Pilot menu and select Pilot 4. Now use the keycard information you collected above and create a program that allows only one key card to unlock the door. Download and test the program. Set the program for Continuous Run and test it again. Can one of your friends get in without the right key? ACTIVITY 6 PAGE 25
