Rc Car Ez-fied

1 of two motors without gear box.

and steering which will be heavily moded. by the way, does anyone have a script that will let you control the servo and when you let go it will move back to centre? going to use custom movement panel.

need a command that will cue the sabertooth forward and reverse in the custom movement panel.

will the Forward() command cue the sabertooth motors forward?

amperage might be too much for one port

1 motor is 2.8-3A running and 6A jump at start 2 on one im not so sure about.

i need a diagram of the sabertooth connected to the ez-b.

Check the Tutorials for help.

The EZ-B connects to the GND, +5 and Signal to the Sabertooth. The Signal from the EZ-B connects to S1 on the Sabertooth.

Every control has a question mark next to the close X button. Pressing the question mark button will direct you to a tutorial page for the respective control

have you seen a pic? i read that theres two channels/cables.

shows it in the vid i posted:

ARC supports Simplified Serial Mode at 38400 baud rate on the configured port.

All of the information needed is on the help page

It only needs one Signal Wire connected to S1 on the Sabertooth. The Sabertooth H-Bridge control only has the option of using one port.

ok. when i'm not broke and get the sabertooth ill experiment. mostly understand the instructions.

entire back is done and it looks great! lots of dremeling though. went from one motor to 2 with gear boxes. Will post pic later.

@Technopro

Rich is correct. Each EZ-B port has a +5v, Gnd, & signal pin. You will need to hook the signal pin of the digital port you are using to S1 on the Sabertooth. You can also power the EZ-B using the 5V and 0V terminals on the Sabertooth if you want to. If you choose to power your Sabertooth separate from the EZ-B then one thing you must be sure of is to make sure they share a common ground.

so like this?

sorry wrong pic

is this right? ^

this is the diagram for 2 sabertooths to a microcontroller

Hello?

Can't say for sure, but it looks like your missing S2 connection. However, one tip I can give you is that the dc motor used in the front steering, even the whole front steering gear box will not give you satisfactory results. I't won't hold steering tight. I removed mine and put a servo in it's place. It is well worth it if you can find a fit to place the servo. If you just want to get down to having an RC car. I'll sell you my rc car chassis with the servo steering and an H-bridge so all you have to do it connect it to your EZ-B and download my RC car project. 28 USD if your interested.

i have a metal post in place so the servo can steer the wheels.

Technopro your drawing is correct. This is how I am controlling mine. You will have to experiment with the numbers mentioned earlier to get the speeds like you want. S1 will control both motors depending on how you enter the numbers in the config screen.

thanks everyone.

i have completed my rc car phase one.

servo is mounted.

just waiting till my -$30 becomes +$120

after my wall-e failure I came up with a very cool idea.
mount the top half of him on the rc car shell, and make it easy to remove so I could have just the rc car if I wanted to.

@technopro how did you modified the steering ?
