Robot Kit – Day Six

Oh the wonderful things a robot can do

It can go CHOO CHOO

It can go BEEP BEEP

I’m going to resist making any more mods until you suggest them. I also want to give mama a chance to tinker. Because she said, “But I wanted to do the BEEP!”

One thing we might have to do soon is give Bao a bumper. The ultrasonic sensor takes a beating from all the crashes. Anyway, with the new 3-wheel configuration, we haven’t had to recharge it for 3 days. The 4-wheel tank ran empty in just one day. But then again, we’ve only been in IR mode. Maybe the Ultrasonic processing is a power hog too.

And finally, it was time for new batteries. I strapped some Legos to the frame. You put "one door for going in, and one door for going out."

  1. Hi there,

    I’ve seen you had success with the buzzer and i would like to ask how.
    So far i tried with the sample test program, but it’s only tickin’ like a clock (also very-very silently).
    Later on added the tone(33,9600); after the buzzerOn(); but was the same tickin.
    It’s possible that mine is defected, but hearing the noise i’m suspicious about the frequency.
    Maybe do you know also how to set frequencies?

    Bests,
    Greg

    • Hey Greg, sorry for the late reply! I didn’t realize I had comments. Yes, I also got the the tick-tick-tick-tick when I abused the buzzer too much. But it’s fine if I am nice to it. Here’s how I made the “A” or “Power” button of my IR remote to beep:

      case IR_BUTTON_POWER:
      buzzerOn();
      delay(100);
      buzzerOff();

      You can try uploading my Arduino sketch here:
