Arudino, PS3 USB Host Shield, and Motor Shield

Using Arduino General Electronics
#1

Hello, I’m making a PS3 arduino to control the Pan/Tilt control for Camera Jib.

Here’s what I have so far… I have the zoom in/out working fine but the problem is the motors. The Jib gives a constant power that locks the motors so they stay in place unless you move the joy stick. I don’t know how to do that with the arduino. I can move the camera left to right but with no power applied to the motors, the then free falls.

So far

//y = PS3.getAnalogHat(LeftHatY);
//x = PS3.getAnalogHat(LeftHatX);

Serial.print(F("\r\nOSC did not start"));
while(1); //halt

Your video shows servos, but the code is for DC motors...?

Hey Mark, the servo is controlled the PS3 Right analog for zooming in/out that's working fine.

if(PS3.PS3Connected || PS3.PS3NavigationConnected) {
servo1.write(map(PS3.getAnalogHat(RightHatY), 0, 255, 20, 90));
}

I didn't make a video yet of the motors which will be controlled by the PS3 Left analog.

Have you been able to finish this code for DC motors?

I'm also trying to control a TANK-only vehicle using the left control of the PS3.

But I want to control the speed and Giro too, and for this I would need to use the MAP function ..

Did you get adjusted?
