Wait Time Touch Light Sound Ultrasonic Wait till the touch sensor is pressed. Wait till the sound sensor in port 2 hears a sound greater than 50.

Loops Forever Sensor Time Count Logic Sensor controlled loops Time controlled loops

Switch controlled by values The switch takes an wire input at 1 If the condition is met the upper path is taken, otherwise the lower path is executed.

Switches controlled by sensors The value of the light sensor in port 3 is read. If it is greater than 50 turn right, less than 50 turn left.
