Ping))) and BOE-BOT

I got a package from Parallax containing Ping))) sensor, Pololu motor controller, and a standard servo. After running the ping-demo program and finding out that it worked, how can I write a PBASIC program that causes the BOE-BOT to back up and turn when Ping))) sensor finds objects that blocks the BOE-BOT?

    jeffrey,

    ·· You would need to combine the code for both devices so that the PING code affects the operation of the motor controller.

    Let's say that the program for the Ping))) sensor finds out that the BOE-BOT is five inches from a wall, the program backs up the robot for a second. I want the program to randomly turn the robot left or right. I looked up the RANDOM command in PBASIC online help but how does the program generate a random number of 0 or 1 for the ON GOSUB command?

    just RANDOM a bit variable like this before the ON GOSUB

    RANDOM bitvar

    just make sure that the variable is declared before using

    I took some code from the random.bs2 program and combined it with my code for the robot program.

    Buenas yan Hafa Adai Mr. Savage, the whole ping commands are pretty confusing. In detail can you tell me about what exactly pings are supposed to do.

    Think of it as a Sonar in a Submarine. The Ping sends out a signal. When that signal hits something in its path it "bounces" back to the Ping giving you the reading.
