Re: Arduino+Brushless Motor Problem
It is brushed. Is it possible that I am triggering my ESC's low voltage mode as my battery may have a low discharge capacity and is not up to the task of running the motor at full throttle?

Re: Arduino+Brushless Motor Problem
Do you have more information? eg what motor esc battery are you using, what is the weight of the vehicle, etc
Re: Arduino+Brushless Motor Problem
Yes, I should have posted that to begin with. The motor is a Traxxas Titan 12T 550 size and the ESC is a Hobbywing Quicrun 1060. The battery is a Tenergy 7.2 Volt NiMH 6 Cell. I think I may be having brownouts with the Arduino as more load is placed on the vehicle. This would cause the Arduino to reset and re-run the program. I am going to try and power the Arduino seperately and see if that can solve my issue. Do you have any other suggestions?unwoundmouse wrote:Do you have more information? eg what motor esc battery are you using, what is the weight of the vehicle, etc
Thanks for the help and replies during the Summer!

Re: Arduino+Brushless Motor Problem
Based on the symptoms you're currently having, I would place my bets on a voltage drop as well. I assume currently you're powering the Arduino with the ESC's built in BEC?
Re: Arduino+Brushless Motor Problem
Yep, I was powering the Arduino with the BEC. I am now powering the Arduino with a 9V battery and everything is functioning properly.unwoundmouse wrote:Based on the symptoms you're currently having, I would place my bets on a voltage drop as well.

Re: Arduino+Brushless Motor Problem
The ESC should have an optional voltage cut off which you need to turn "off". Since the rules state that the Arduino controlling the motor must be powered by the main battery supply, attach separate leads to the battery and run them through a voltage regulator and then to the Arduino. My vehicle from nationals used this kind of work-around and it fixed the Arduino-resetting problem. My vehicle is posted on the best of nationals page if you need a visual

Re: Arduino+Brushless Motor Problem
Thanks for the reply. I found the rules clarifications on the Soinc website and see that it says that a battery may be used to power the motor, and another battery may be used to power an Arduino.

Does this mean that I can power my Arduino from a separate power source (9V battery), and power the motor with a different power source?
Thanks!

Re: Arduino+Brushless Motor Problem
It seems like that would be legal, yes. I was not aware of this clarification before nationals so I had to do it the harder way, but either way, it should not effect your vehicles performance.turb0lag wrote:Thanks for the reply.
