 Motor Synchronization In programming motor synchronization, I find myself typing the following code (or a variation of it) every time I want motors B and C to go straight:
nSyncedMotors = synchBC;
nSyncedTurnRatio = 100;
motor[motorB] = 50;
wait1Msec(4000);
Is it necessary to use the above code EVERY time I want the robot to go straight, or is there a way to type the code only ONCE and make it apply to all of the code that follows it?
Thanks,
rail33

Hi rail33
You only need to write the nSyncedMotors and nSyncedTurnRatio once, and it will be remembered through the rest of the code. Here is a code snip it I just put together for you. Let me know if this helps B-)

Starwarskid,
Shouldn't you be controlling the speed of the motors through motorC, not B? Either that or change the nSyncedMotors = synchAC, to synchAB.
Regards,
Xander

no:
synchBC; master=B, slave=C !

It looks like I had a typo, but it is correct now. Sorry for the confusion B-)

Confusion is a permanent state of mind for me.
