How can i program a motor to do something like this video?

Thanks so much! Im using robotc btw Which is what you wrote it in i think. im not sure im new to this but thanks for the help!

No problem! The code was written for PROS which is similar to RobotC, but functions a bit differently, so the code would translate to RobotC something like this :

void ReleaseMarble() 
{
         motor[motor2]=127; //Turns motor 2 on at full power
         wait1Msec(500);       //Waits half a second (adjust value until it works with the robot in practice)
         motor[motor2]=0;   //Stops motor 2 
}

(The name ‘motor2’ just depends on how you’ve named the motors in the Motors and Sensors menu)
Then you can call the function anywhere else in the project with the line ReleaseMarble();

will this automatically start, and then stop and then start again?

No, you need to put it in a loop to get it to do it repeatedly

int marblesLeft=10;               //This variable keeps track of how many marbles are left, I used 10 for example

while (marblesLeft>0)    //This block will keep looping until no marbles are left
{
      ReleaseMarble();         //Calls the function for releasing the marble that is defined somewhere else in your code
      marblesLeft=marblesLeft-1;       //Subtracts 1 from the marble count each time it loops round
      wait1Msec(1000);        //Waits a second before the process continues to loop again
}
 

It will start automatically if you put it in the user control task in the while(true) loop

Can you explain it more in depth I’m not understanding this can you remove the releasemarble, marblesleft, etc
