I'm trying to make a simple Mindstorms robot that will act as a turret using an infrared sensor. The goal is for the robot to just turn and scan the environment and when the infrared sensor detects the beacon, it will stop. I was wondering how I would go about in coding such a robot.

Which infrared sensor?

The Lego Mindstorms Infrared Receiver seen here: http://shop.lego.com/en-US/LEGO-MINDSTORMS-NXT-IR-Receiver-2855040

I would start turning the motor, go into a loop, and continuously check for a signal. If a signal appeared I'd break out of the loop and tell the motor to stop.

Are you using RobotC? (I guess you would be, since you're on this forum)

I am using RobotC but I am not very experienced with it and it would help if I could get an example of this code.

That sensor is designed for sensing the signals from a power functions remote. I don't think it'll work as a beacon detector.

That sensor can be used as a sensor for the FTC beacon. You can use the built-in drivers but you have to enable a few things first. First put ROBOTC in expert mode like this:

After that, you have to enable access to these sensors:

Make sure the line with HiTechnic in it is ticked.

Now you can select the sensor (either 600 or 1200 Hz) from the list

Alright, I have the Lego Infrared Seeker, can I get a sample of how I would code what I want with this?

Read the sensor's data with SensorValue[]. Experiment with simply displaying its value on the screen to see what kind of numbers it returns.
