OK, I installed the PWM Movement panel. I did not put the jumper as I have to take the robot apart. I was hoping to be able to just work with the cables. It worked before with only four wires.

here's what I have so far:

Reverse works =Perfect. Left turn works=Perfect Right turn works b=but with a wide curve using reverse added to it. Forward works= but with a wide left turn added to it.

I feel I have it halfway there.

Please don't tell me I have to disassemble.

:-) Thank You!

I wanted to say, when I adjust the panels for PWM, I only get ONE slider to work at a time. I switched ports and the other slider works. If that helps any.

Before I took Sally apart, It was working perfect without any PWM controls. No jumper changes and no extra ports and cables. Why would it change all of a sudden? There are only four wires, but there are SOOOO many combinations that you can put them.

Thanks! :-)

I'll have to wait. Sally is running hot. The EZB And the port is not seen by the computer and I burned my hand on the heat Sink.

You didn't need to touch the existing cables at all. Yes, you would have to open the robot up and access the motor controller. If you had any change it was pure luck. If you simply added a PWM control nothing should have happened.

If you did in fact touch the wires and wired it wrong, you could have been feeding 5vs into the ez-bs signal line, which is bad.

Ok, It will be Tues before I can try it again. OK, so it is take apart again. I should have left a place to access the wires. I may have burned up the port on the ezb because I can not find it anymore. If push comes to shove, I will us V4 and keep on truckin'.

Thank You SSOOOOOOOOooooooo much for your help! :-)

For the scripting, for example Forward,

Use this, and modify the speed until the faster motor is the same speed as the other.

#Forward
set(d13, on)
set(d12, off)
set(d11, on)
set(d10, off)

#Change the port to the one you pluged EnA into.
Pwm(d15, 90)

#Change the port to the one you pluged EnB into.
Pwm(d16, 100)

#Change these speeds until the robot drives straight.
#Remember you want to slow down the faster motor
#which is the one on the far to the way it turns.
#I.E. It turns right, left motor is faster.

Link to the project i made for you. Load it, and connect to your Ez-b, and test, or import it straight into your current project.
