Stepper Motor Circuits
?» The stepper motor driver Creative Works of Tom McGuire
This is designed to work with a varity of stepper motors, 5 or 6 wire unipolar types. Its also made to operate from about 9 volts to up to about 24 volts. Below is a bread board layout of the circuit but I can offer a PC board layout for those of you who want something a little more professional. You will need 3 of these for the X, Y, and Z motors

Maximite Stepper Motor Interface
Bipolar Stepper Motor circuit
So I had a lot of trouble figuring out that the Source pin goes to low voltage (source of electrons) and the Drain pin goes to high voltage (absorbs electrons). Basic electricity, but it still took me a while.
Driving a Bipolar Stepper Motor with Arduino and ULN2803AG
While I`m getting ready to rip open some 10+ broken DVD-RW drives coming to me from an eBay seller, I though it would be great to have a testbed for the bipolar stepper motors I will harvest from those. I have a bunch of ULN2803AG Eight Darlington Transistor Arrays with Common Emitters left from past projects and these can sink (but unfortunately

Add Ramp To Stepping Motor
Due to their low cost, stepping-motor controllers are often chosen over full-blown, software-driven controllers for a number of applications. However, stepping motors provide rather low torque at high speeds, thus they usually require a starting ramp to prevent them from stalling at startup. This circuit is a one-chip solution to that problem.
Stepper Motor Driver
These have two coils and are controlled by changing the direction of the current flow through the coils in the proper sequence. These motors have only four wires and cannot be connected to this kit. See our Kit 1406 for a Bipolar Stepper driver Kit. 2. Unipolar motors. These have two center-tapped coils which are treated as four
Stepper motor getting very hot wrong driver or power supply
The ULN2003A and Zener from the driver board inside the same device. It`s a 5 wires motor, but the one in the schematic is 6 wires. I suppose the only difference is that the 5 wire version has the two center taps joined together so that`s what you see in my schematic. The motor seems to run perfectly, however after a minute or so it becomes...

EQG MOD FOR DIRECT STEPPER MOTOR ACCESS
The modifications involve direct access to the stepper motor controls of your mount. Any "mis-control" or "mis-command" / "invalid parameter" or "garbage" data sent to the mount could accidentally activate the stepper motors and allow it to rotate "freely" damaging any equipment connected to your mount. It is also possible that any garbage or
Stepper Motor Circuits
To control a stepper motor, you have to energize each winding individually in a specific and timed order. The energizing is accomplished by a driver circuit (an amplifier). The timing is performed by an indexer circuit and the objective (go forward, go backward, brake, coast, etc. ) is controlled by some external user interface, such as a computer
3 axis stepper motor controller for pc parallel port
driving stepper motor using uln2003
The simplest way to drive stepper motor having lower current rating is using ULN2003. The ULN2003 contains seven darlington transistors. The ULN2003 can pass upto 500mA per channel and has an internal voltage drop of about 1V when on. It also contains internal clamp diodes to dissipate voltage spikes when driving inductive loads. The circuit for
In a traditional microstepping motor controller, many parallel outputs of a microcontroller are used which are then converted to analog signals using a DAC and fed through a power amplifier to the motor coils. This approach is inefficient both in terms of the power consumed and the number of GPIO`s used thus increasing the design complexity. Our...
stepper motor controller using pic16f628a
Since I finished my degree in April, I have been looking for work. The search has been slow but hopefully soon I will be making the big bucks. To fill my s..
stepper motor controller circuit and code
A step motor controller based on the schematics found on the Arduino Web site. First I try the 2 pins one for bipolar stepper motor. I wont be able to make it work, even less with the library available on the site. Maybe I`m dumb and I really dont understand something, but this circuit keeps both coils active at the same time. So I tried the...
maximite stepper motor interface
This simple circuit and program listing allows the Maximite microcomputer (SILICON CHIP, March-May 2011) to control a stepper motor. It could be expanded to allow for the control of multiple motors, with four of the Maximite`s external I/O pins used to control each motor with identical driver circuits. A ULN2003 Darlington transistor array (IC1) s

circuit explanation of stepper motor
Darlington connection-type transistor is used for the drive of the coil. As for the Darlington connection, 2 stages of transistors are connected inside in series. The "hfe" of this transistor is the multiplication of the "hfe" of each transistor inside. In case of 2SD1209K which was used this time, the hfe is over 4000. Because the ratio of the in

stepper motor driver circuit diagram
Using L297-L298 integrated circuits manufactured by SGS Thomson (ST) can be made a control circuit for a stepper motor with two phase bipolar or unipolar four-phase (maximum current allowed on stage is 2 A). This integrated motor driver generates control signals for the double stator and allows selection of travel direction and execution of a full
A footstepping effort-based locomotion interface is described. Built around an inexpensive and readily-available exercise machine, it provides an effective interface to walk-through VEs..
The resistors R18 and R22 that should have been connected to pin 8 of U4 were mistakenly connected to pin 9. The present versions have been corrected. A minor error on the component layout is that there are two versions of C2, in the upper right and lower left corners - let one of them read C11 instead (they are equal). This is not corrected on...

Ultrasonic distance finder circuit
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is measured. There are three main categories of distance measurement methods in use: a) By...
Simple Metal detector circuit with CD4030
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to find something potentially valuable, hidden a few centimeters below the soil. So many...
Fully automatic watering circuit for flower pots
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This circuit comes as a solution to this problem. Depending on humidity of the pot at...

With the circuit of this metal detector, it is possible to detect a metal coin in depth of 90 to...
Sub-Harmonic Bass Converter for Electric Guitars
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound, such as filtering or distortion. Instead, a frequency division system produces outputs...
Echo Depth Sounding Sonar for Boats
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the calibration of the rope. This arrangement still exists in some yachts. The big...

This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power supply must be symmetrical so that no electrolytic capacitors are needed at the outlet....

Analogue Sound Preasure dB-Meter Circuit
The best human ear can capture sounds from 20Hz to 20KHz. These limits are known to be the broadest that can exist. Normally the normal limits range from 100Hz to about 13KHz and depend on the age and health of the individual. We for our measurements and to have a good accuracy we will get the limits of 20Hz to 20KHz. A sound to be heard does...
