GETTING STARTED<br />
ACTIVITIES<br />
The Burglar Alarm<br />
Learning Objectives<br />
Students will:<br />
Build a working alarm system for the house using light sensor feedback.<br />
Program the alarm system to work using Pilot 4 (or higher).<br />
Create a motorized device to scare intruders!<br />
Program multiple output devices to respond to one input.<br />
Discussion<br />
In the Ceiling Fan Activity 3, you will find an example program for<br />
checking the light sensor values using the RCX View Display.<br />
Here is an example of a four-step Pilot 4 program that waits for the light<br />
sensor to be activated (input is less then 50 — students need to use their<br />
own number here).Then it flashes the lamp on and off and back on.<br />
The program is set for Continuous Run so the first step of the program<br />
running again is to turn off the lamp.<br />
Students can flash the lamp on and off more times by adding more steps.<br />
They can also adjust the power level of the lamp.<br />
