Builder Programs

Thermostat
This is a temperature feedback program (thermostat) using Builder. Step 1 waits until the temperature sensor on port 1 senses that it is above 70 degrees before moving on to Step 2. In Step 2, motor A turns on at power level 5 (the LEGO fan blades are connected to the motor) until the temperature goes back down below 70 farenheit again.




Engineer Programs

Color Reader
This program is for the color reader, one of the seven LEGO models that come on the instruction booklets for LEGO Dacta set #9701, the Control Lab set. The front panel indicates whether the LEGO piece that passes by the light sensor on the conveyor belt is blue or yellow. You can also turn the conveyor belt on and off from the front panel.
