Custom Parallax C3Bot

I re-purposed a "Robot Shield w/ Arduino" kit tonight since I just never did get into the Arduino. So I took the Parallax C3 board I had, stuck it on the chassis, mounted the PING))) Mounting bracket kit, and the Tank Tread kit. Here's to hoping I can get it working good and improve my programming skills! :)

    You're off to a promising start! Now let's see a Figure 8. :)

    Thanks for your vote of confidence, Erco! I sometimes follow your posts on here, wish I had half the robotics knowledge you've amassed. ;)

    I played around with it a little last night, got the Ping))) to work when I figured out which pin it was hooked to on the C3 and changed the code. I haven't got it to drive yet, so I must be doing something wrong. Not sure if it's because the pin numbers are different for the servo connectors or if it's because the C3Bot doesn't have encoders like the ActivityBot does. My regular ActivityBot works awesome, and I was just trying to port the code over to the "C3Bot" but obviously I will have to change a lot of things to make it work, I guess.

    Welcome to someone who came from the other side.
    A lot of potential possibility's there now. You have the space and the power to use it. Now the real fun begins.

    Thanks! :) Looks like the Arduino gets a lot of love out there, but couldn't find any reason to use it over the Prop - more the other way around, I think. Anyway, back to my C3 board creation, I figured out how to change the pins for the servos to the motors and got it to fire up the tank treads...and then I promptly realized why the C3 isn't really a "robot control board". It's only got a 2 position switch. :D haha! Don't think that's going to work too well here. The switch has to be in the ON position to get it to sync to the computer and download, but then it wants to run the servos while it's doing that.
    Oh well. I guess maybe I should just save the C3 for some other project and use the regular Activity Board WX on the regular ActivityBot I have for now.

    Wait a minute, you can always add a switch to energize your servos, their power is separate except for ground and signal.

    OK, thanks. Didn't realize I could do that with the way the pins on the C3 board are separated out. I'll have to look into that one, but for now I should probably just stick to the "regular" ActivityBot setup so I can learn some programming where I have easy examples.
    Honestly, after reading tons of posts on here, I think I'm going to have to bite the bullet and start from scratch. It's been a LONG time since I had any kind of physics/electronics class. I probably need to start completely over and learn from the capacitor and diode up the chain! :D haha...there goes my next year of "free time", right?
