BluTooth Tutorial
This is a Tutorial/ Robot Project all mashed into one. The first part is the BluTooth, and the second part is the robot to go along with it (Robot may not actually be present). In this tutorial, you will learn how to connect and use 2 NXT's with the built-in BluTooth connection. Now, lets get on with it!

Step 1: Making the Connection

First of all, of course, you need 2 NXT bricks. Second, plug them into your computer with the USB plug. Then, change the NXT names to : "NXT 1" and "NXT 2". Without these names, the program will not work. (The first program is the program for "NXT 1". The second program is for "NXT 2") When your all done, have fun and ENJOY!! Oh, and you can also make your own BluTooth programs!

My Robot

My robot is an RC car. It uses BluTooth to control the car with the remote, and it has a cannon on the top! The 2 back wheels dont have rubber on them, just so that it drives better. It also has two lights.

  • I don't have two NXT's, but I believe the program would work. Good job!

  • I don't know how you can call this a tutorial. You have explained very little. That aside, the programs will not work. The touch sensors in the send (NXT1) program have no effect. Both loops will send out a continuous stream of on/off messages. The receive program (NXT2) is similarly flawed. The message receive blocks have no effect on the loops. The loops will cycle rapidly turning the sounds on and off with no regard to whatever messages may have arrived.

  • Now to fix the programs. NXT1: Replace the Touch Sensor blocks with Wait blocks (configured to Touch Sensor). NXT2: Each Sound block needs to be inside a switch. The Yes/No output from each Receive Message block must be wired to the switch. Tip: It is a lot easier to change the name of the NXT brick in the Bluetooth connection block, than to change the name of the NXT brick.

  • Norama: Listen. I havent been using NXTs for about 3 months, since I last made a WORKING BluTooth connection! Therefore, my knowledge of the MINDSTORMS Software is a little sketchy. Im sorry about the flaws, but one of the things was to try to fix it up yourself (in the program). But thank-you for alerting me about the flaws, I appreciate that.
