Controlling a Brushed ESC

Hello, I am new to ESC programming and I wanted to control a 3V DC motor with this ESC:

https://www.amazon.com/Bustophedon-Brushed-Speed-Controller-Truck/dp/B017TRZ6IW/ref=pd_sbs_21_2?ie=UTF8&psc=1&refRID=TS6DHGRBA2V1C4PWMHRD

I am having trouble setting it up and I can't find documentation or guides for brushed ESCs. I am using an Arduino Uno, please advise me on how to set up and program it.
This is testing for building an ROV and I hope to extend it to use a 12V DC motor.

Also, I have a 9V battery available for use and the power to the Arduino, if this helps.

Please help me on this, it's urgent. Even just code helps; I think I've got the wiring down now.

Thank you.

You are using the Servo library right?

What have you tried so far? You understand ESCs have arming sequences for safety - they wont
just start at full power.

I am using the Servo library. What I can't figure out is how to arm the ESC. I got it set up correctly today, but it just keeps powering the motor and un-powering it- slowly.

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

Thanks.. Tom..

Have you experimented with a servo tester like these?http://www.ebay.com/itm/1pcs-multi-Servo-tester-3CH-ECS-speed-controler-Power-CHANNELS-CCPM-meter-/172214381958?hash=item2818c6ed86:g:x0sAAOSwq19XBdIG
A bit of a play would quickly identify a reliable arming sequence.

Try using 0 degrees for a couple of seconds then slowly ramping up?

And you have a 2S ESC (ie requires 7.4V LiPo battery as power source), and claim to be
driving a 3V motor. I don't think your motor will survive at that power level and I'm sure the
ESC needs more than 3V to work.

I basically have the circuit down, but not how to arm the ESC.

Here is the code (I found it in a guide for a brushless ESC that says to send values of 2000 and 700 and listen for sounds, it looks useful):

// This program is supposed to control the speed of a brushed motor through an ESC with the Servo library, input sent through Serial.

#include <Servo.h>

Servo ESC;

int value = 0; // value sent to the ESC

void setup() {
  ESC.attach(13);
  Serial.begin(9600);
}

void loop() {
  ESC.write(value); // send the value to the ESC, always starts at 0

  if (Serial.available()) {
    value = Serial.parseInt(); // read a number from the Serial monitor is it's available
  }

}

I will try to send different values with the code above to see if there are any results. What would you suggest I send?

I have attached the circuit as a PNG.

I just use the "Knob" example in the Servo examples.

You need a pot to use it but it works just like a throttle on a r/c .

Maybe alter the sketch to print the values to the serial monitor.

Nothing seems to work. I can't figure out how to arm it. Maybe I should try a different ESC?

Hi,

PLEASE LABEL EVERYTHING ON YOUR DIAGRAM, WHAT IS THE RED BOX THE POWER IS EMINATIING FROM???

Tom.... :o
