Motors, Mechanics, and Power / Re: ir2110 problems

If you're driving a motor in one direction from 14v , why bother with a !R2110?

Just use a suitably rated logic level mosfet driven by the arduino - with a catch diode of course.

Or if you require reversing there are many H-bridge shields available.


Thanks saximus,
Sorry, I am not programmer, If you tell me what to change with what or complete detail , i would appreciate it..........

Thanks again
Don't see why that wouldn't work, on Arduino:
Code: [Select]
digitalWrite(outPin, analogRead(aInPin) > 400); // about 2V

Well, you seem to be redrawing the menu every time through loop(), which might happen thousands of times a second.

Code: [Select]
void loop() {


I think you will blow way past your 20km per hour speed if you do go wide open throttle. Thats 2+ horsepower!

But does it fix Nick's "bootloader programmer" ability to burn the bootloader?
It sure seems to. That's the first part of this whole process. Unfortunately, the second part, flashing Arduino code (e.g. "Blink") to the IC remains elusive.

I don't have the answer, but I want to help. So if I read your question right you want the stepper motor to continue spinning until the button is pushed the second time? What is it doing now? I just learned that if you put
Code: [Select]
at the beginning of your code and /code "in the same brackets as the first code" it will make it easier to read. google code tag.

that's all I have good luck

You need  to get away from trial and error and really learn the block syntax.
These two lines need braces around them to form a block for the "if":
Code: [Select]
    delay (2000);      // our work is done - pause for a while
  resetSuccess = false;
