That is super cool. On some of the earlier versions the STEP pin is not labeled, and the motor coil output pins are not clearly marked. N.A.

Here N.A. Hi Anthony,Different motors have different levels of torque. If you cut jumper APWR (SJ1) then you can use the 5V pin as a VCC input to the Easy Driver, powering it with your own VCC supply. You need a special amp meter attachment for a scope.
If you want the EasyDriver to power some small circuit, you can use the 5V (or 3.3V) coming from pin 1 of JP4. A15) Well, based on user's e-mails to me, there is a lot of confusion about this pin. With regard to the delays surrounding a STEP pulse.
It is very, very rare for people to use the APWR jumper. That’s 500,000 Hz. My only “gripe” is that it could use a spare ground connection next to the step input to simplify wiring. The Easy Driver is basically just a breakout board for this driver chip, so the datasheet is your best source of information about how it all works.

However, if all you need is a reference to the pins, here you go: GND : There are three GND (Ground) pins on the Easy Driver. https://vimeo.com/1708760 Eastern Geek 122,420 views 1:33 How To Control a Stepper Motor with A4988 Driver and Arduino - Duration: 9:35.
FAQ Q) How do I adjust the current limit? In both case (full and half steps) the current can are limitated to the winding resistance. The voltage spec of the motor doesn't really matter, using the EasyDriver. (Or any chopper driver, for that matter.) The EasyDriver will ramp up the voltage to the coil until the Loading...
The 3/5V jumper (SJ2 on the schematic) comes 'open' from the factory (no connection between the pads) and thus is supplying 5V to the driver chip, and thus by default the http://wiki.seeedstudio.com/wiki/EasyDriver_stepper_motor_driver_V3_-_assembled EasyDriver V4.3 - Exactly the same as V4.2 except two mounting holes have been added based on user requests. What tool is designed to turn the current adjust pot? And I just built my stepper setup last night using the same driver!
It was indeed, an "EasyDriver" to set up ;) PLEASE NOTE: some people have overlooked the extra (ground) pin on the easydriver board. http://freedesktopwallpapersite.com/easy-driver/easy-driver-pro-key.php A14) Sure!

More about the author ok this is the theory.
I have to add a 555 generator for the step input? Thank you and AWESOME tutorial. A quick tutorial on how to get things up and running with the EasyDriver v3.1 Stepper Motor Driver Board.
Yup, the EasyDriver's 5V regulator has some extra juice, and so we brought out the 5V output of the regulator for you to use if you want. Measuring this voltage allows you to calculate the actual max current being supplied to the motor. Normal PWM just varies how long the signal is high, as a % of the total time. Samuel,Just add an extra delay after you pulse the motors high.
EasyDriver V4.4 - Exactly the same as V4.3 except the MIN/MAX silk screen error has been fixed (well, not really, since the current adjustment pot got changed) See note Q9 below. ProtoPICVideos 40,195 views 6:07 Arduino Stepper Motor Control - Duration: 7:16. EmbeddedMan / about 8 years ago / 1 / Your wish is my command! click site The chip on the board can do half and single steps as well, but the board is not configured to deal with that.So if it's speed you are after over precision,

The pwmout command takes the pin, the period, and the duty; for example, to yield 10,000 Hz with a 8 MHz resonator use: pwmout 2, 199, 400. A) Just turn R16 - the 10K current limit pot.

I never do this myself - I adjust the pot until things 'feel' right on my motors since every situation is different. The reality was I was spending excessive amounts of time in getting the setup and control part working and not refining the code that does the actual moov.Now I just pass Then it would be easy to wire up as many EasyDrivers as you wanted to drive lots of stepper motors. However, you can normally get away with less than that and still be just fine.
SparkFun Recommended Programming Interactivity - 2nd Edition Only 4 left! And how do I know which way to turn the current adjustment pot? Also the voltage regulator gets quite hot - this is because the driver chip needs 70mA at 5V for its logic supply. In terms of the 4 holes on the EasyDriver v3 board, looking down, all of the following color assignments give clockwise stepper rotation when the DIR input is high: (R=Red, G=Green,
Have you verified the output with a logic analyzer or scope? This little guy will draw the current you set it to no matter if it is moving or not. Knock-Off Easy Drivers Over the years, the Easy Driver has become popular enough that lots of people have copied it and are making and selling it.
