What you need to get started What is a stepper motor and why should you care? A stepper motor is an electrical motor that turn in steps, this is in contrast to a conventional motor that moves smoothly. The steps are measured in degrees and vary from motor to motor.
Arduino Tutorial: Stepper Motor with. The wiretable for Arduino EasyDriver Stepper motor. Actually I’m after a full work flow for using easy driver with. The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder.
So, why do you want an “unsmooth”-motor? Because you can do awesome things! Since the motor moves precisely x amount of degrees per step, you can easily control just how much it is going to move, and easily count how much it has moved. For example the motor I am using in this tutorial moves 1.8 degrees per step, this equals to 200 steps for a 360 degrees rotation. Fabulosos X-men - Hqs Comics Completo Pt-br Hq Torre. (Each step is then divided into minor micro steps, so in reality it needs more micro steps to turn 360 degrees. (Mine needed 1600 steps)) This makes the stepper motor perfect for applications where you have to move something precisely, and to know the position. Great, I’m ready.
Mr Destiny Ita Yahoo. Hook the hardware up like this. This is what it looks like when everything hooked up. What about the heat, adjustable current and cables? As we were working on the project were the stepper motor was going to be used, we came across some challenges related to the motor getting really hot, how we were going to adjust the current controller and how the h**k we were going to connect the cables when there was no explanation on which cables was what in the datasheet. Well, you are probably asking your self some of these questions. Don’t worry; we got you covered in the section below.
Too hot to handle? Don’t worry if the motor get’s hot. It isn’t damaging for the motor until it reaches around 90 degrees Celsius (194 degrees Fahrenheit).
For a comparison: When our motor was too hot to touch for more than 2 seconds, we measured it to be 55 degree Celsius (130 degree Fahrenheit), so it feels very hot even though it isn’t damaging. Even though it can handle the hotness, an electrical device thrives when in a colder condition, and therefore you should turn the motor off every time it isn’t used (moving or holding). This can be achieved with the ENABLE pin on the EasyDriver (as in the “sex and cigar” code snippet). The adjustable current controller On the EasyDriver there is an adjustable current controller. This goes from 150mA to 750mA. The motor I am using in this tutorial operates at 350 mA, so I turned the controller a little under half way up (I did it the non-scientific way and used my gut feeling). A simple rule is this: More current equals more torque, more heat, less speed and more motor noise Less current equals less torque, less heat, more speed and less noise How to apply the rule; turn the current all the way to MIN, and turn it gradually up to the point where the motor no longer skips step(s).
