Hi, This is a straightforward match for my **16 years of embedded/automation experience** with Arduino, STM32, stepper motors, drivers and motion control. I have completed projects involving **stepper/servo control, industrial actuators and automated machine sequences**. I can provide a clean Arduino Uno sketch using **AccelStepper**, with clearly defined constants for: * 200 steps/revolution (1.8°/step) * Micro-stepping setting * 60° travel * Motor speed/acceleration * 1-second dwell times * STEP/DIR driver pins The sequence will run continuously: **Home → +60° → 1s → Home → 1s → −60° → 1s → repeat** The motion will be open-loop as requested, with no sensors or limit switches. I’ll ensure the step calculations correctly account for the selected micro-stepping value and make the code easy to modify for other motors/drivers. I can also provide a **clear PNG/PDF wiring schematic** showing Arduino Uno, STEP/DIR driver, motor power supply, motor connections, common ground and opto-isolation/resistor connections where required by the specific driver. Please provide the **stepper-driver model and supply voltage** so the wiring diagram matches your actual hardware rather than assuming a generic interface.

Hi there, I can deliver the fully tested Arduino sketch and a precise wiring schematic for your Nema 34 stepper system. An important technical note: a standard 200-step motor (1.8°/step) cannot achieve exactly 60° in full steps (60 / 1.8 = 33.33 steps). To hit precisely 60° without drift over time, you will need to enable microstepping on your driver. I will set up the code so you can simply input your driver's microstepping multiplier, and the sketch will automatically calculate the exact pulses needed. My Deliverables: The Code (.ino): I will utilize the AccelStepper library. This allows for smooth acceleration and deceleration, preventing a high-torque Nema 34 from stalling or missing steps during rapid directional changes. All parameters (speed, acceleration, the 1-second dwell times, and micro-stepping) will be defined clearly at the top for easy tweaking. The Schematic: A high-resolution PDF/PNG diagram showing the exact connections between the Uno, your stepper driver, and the power supply, including the correct wiring for the driver's opto-isolated inputs. As an Electrical and Information Engineer with extensive hands-on experience in motor control and hardware design, I ensure safe, reliable wiring and clean, non-blocking code. I can have this tested and ready for you today. Please let me know which specific driver model you are using (e.g., DM860H) so I can label the schematic perfectly. Best regards, Risitha

I can deliver this today as a clean, non-blocking Arduino Uno sketch with a clear STEP/DIR wiring diagram. The sketch uses AccelStepper and a state machine: - +60 degrees clockwise, hold 1 second - return home, pause 1 second - -60 degrees counter-clockwise, hold 1 second - return home, pause 1 second - repeat indefinitely Key constants at the top: steps/revolution, micro-stepping, swing angle, dwell times, RPM, acceleration, direction inversion and input polarity. Calculations are in RPM and degrees, so changing micro-stepping does not require rewriting the motion logic. Deliverables: 1. Fully commented .ino source 2. PNG wiring diagram: Arduino, 220 ohm input resistors, STEP/DIR driver, NEMA 34 coils and separate DC supply 3. README: wiring, DIP setup, tuning, upload steps and safety notes I compile-verified the sketch for Arduino Uno with AccelStepper 1.64.0: 8,954 bytes program and 529 bytes RAM. The included wiring uses common-anode opto-isolated inputs and active-low STEP/DIR; I also provide the exact changes for common-cathode inputs. Price: INR 1,500. Timeline: within 12 hours after award. I will support one round of small adjustments after upload.

@MilosN36

Hi, I can create the complete Arduino Uno solution for your NEMA 34 stepper, including the motion sequence, adjustable microstepping/speed parameters, and clearly commented code. I’ll provide the `.ino` file together with a simple wiring schematic showing the Arduino, stepper driver, power supply, and required connections. I have experience with embedded motor control, stepper/servo systems, and robotics, so I can also make the code easy to extend later if needed. Best regards, Milos

@abrahamgamboa

Hi, I work with Arduino/stepper control regularly. I'll write the sketch using the AccelStepper library so speed, acceleration, dwell times and micro-stepping are easy constants to tweak later, sized for a 200-step/1.8 Nema 34 with your driver's step/dir interface. I'll test the timing sequence (60 CW, hold 1s, home, hold 1s, 60 CCW, hold 1s, repeat) in simulation before delivery, and include a clear wiring diagram (Arduino Uno, driver, power supply, opto-isolators if needed) as a labeled PDF/PNG. Happy to adjust the constant for different micro-stepping settings as you mentioned. Can deliver within the timeframe above.

@Rodolpho41

Hi! I can help you with this stepper motor control setup. Using the Arduino IDE and the AccelStepper library is the ideal approach here for smooth acceleration and precise positioning of your NEMA 34. Here is what I will deliver: Clean, well-commented Arduino (.ino) code configured for open-loop control, with easy-to-adjust variables for speed, acceleration, angles, and micro-stepping. A clear wiring diagram (PNG/PDF) showing all pin connections between the Arduino Uno, your stepper driver, power supply, and any necessary resistors. I am ready to start right away. Let's get this motor moving!

@malindu0027

Hello, I can provide Arduino source code, wiring diagram and a quick video of test running the motor using my hardware. looking forward to working with you. Thanks.

@parikalav

Hi, I can build this directly with the AccelStepper library for clean, tunable motion control. Understanding of your sequence: home → 60° CW → hold 1s → return home → pause 1s → 60° CCW → pause 1s → repeat indefinitely, based on a 200-step/rev (1.8°) Nema 34, open-loop, no sensors/limit switches. My approach: I'll use AccelStepper's moveTo() with position targets calculated from your 200-step/rev base (60° = 33.33 steps rounded appropriately, or exact if using microstepping), and non-blocking delay handling so timing stays accurate. Speed/acceleration and dwell times will be defined as named constants at the top of the sketch so you can tune them easily later, as you asked. Deliverables: fully commented .ino file, plus a clear PDF/PNG wiring diagram showing Arduino Uno, your stepper driver, power supply, and any resistors/opto-isolators needed — laid out so you can replicate it on a breadboard without guessing. Question: what stepper driver are you using (e.g., DM542, TB6600, A4988)? That determines the exact step/dir wiring and whether opto-isolation is needed on the signal lines. I have hands-on embedded systems experience (Arduino/microcontroller projects, motor control) and can turn this around in 2-3 days.

@edgaritoram2

Hello good day Regarding the project, I was able to deliver it in a short time without any problem, except that the nema, since it does not have a rounded step, will be +- one degree unless I make half steps, but that reduces the power by half. If that is not a problem, it can be done easily. I know that I have not done work before, but I have worked on multiple occasions with a stepper motor, so I can fully trust that I will provide the appropriate deliverables in the shortest possible time. Thank you for your attention.

@timileyino34

I will write this project code for you, very efficient and easy to customize when you wish, as major variable parameters will be declared to be easily change, example the angle of rotation and waiting time.

Hi, I can help you build and document this Arduino Uno + NEMA 34 stepper motion loop exactly as specified. I have experience working with Arduino, microcontrollers, motor drivers, embedded systems, and robotics, including integrating motors and dedicated motor-driver electronics with robot controllers. For your project, I will provide: - Clean and well-commented Arduino Uno source code - Accurate 60° clockwise → 1 sec hold → return home → 1 sec pause → 60° anticlockwise → 1 sec pause sequence - Step calculations based on the 200-step/revolution (1.8°/step) NEMA 34 - Adjustable constants for steps/revolution, microstepping, speed and dwell time - Proper STEP/DIR control for your existing stepper driver - A clear PDF wiring schematic with Arduino pin labels - Code structured so that speed/acceleration can easily be modified later, including AccelStepper if desired Since this is open-loop control without sensors or limit switches, I will keep the implementation simple and deterministic while making the important parameters easy to change. I can also help verify the calculated number of pulses for the 60° movement and make any required adjustment after you test the compiled sketch on your hardware. I can start immediately and deliver the Arduino code and wiring documentation in a clean, ready-to-use form. Regards, Amit Maurya

@Peter289

Hello, I can deliver this Arduino Uno motion sequence within two days. I have hands-on experience with Arduino-based motor control and understand STEP/DIR drivers, microstepping, dwell timing, and acceleration control. I will provide: • Clean .ino code with editable constants for steps per revolution, microstep setting, speed, acceleration, angle, and dwell time. • A repeatable 60° CW → home → 60° CCW sequence. • A clear PDF/PNG wiring diagram covering the Arduino, driver, power supply, grounding, and any required resistor or opto-input connections. • Compile and logic verification, plus brief setup notes. Before finalizing the wiring, I will confirm your exact stepper-driver model and its STEP/DIR input requirements. This avoids unsafe assumptions about input voltage or opto-isolator wiring. I can begin immediately.

@cnichifor

Hi, I’m an Embedded Systems Engineer with professional experience at a German automotive company, working with C/C++, microcontrollers, firmware, and hardware debugging. I’m new to freelancing, so I’m offering a lower introductory price. The 4-day delivery includes datasheet analysis, implementation, wiring diagram, and multi-level testing. As a bonus, I can also provide short project documentation explaining the setup, parameters, and how to modify the system later.

@MuhammadQdry

Hello, I can provide the Arduino Uno sketch and clear wiring diagram for your NEMA 34 stepper setup. The firmware will implement the exact sequence you specified: 60° clockwise → 1 second hold → return to home → 1 second pause → 60° anticlockwise → 1 second pause → repeat continuously. I will structure the code so the main parameters are easy to modify, including motor steps/revolution, microstepping, target angle, speed, acceleration, and dwell time. I can use AccelStepper where appropriate to keep the motion control clean and adjustable. I will also provide a legible wiring schematic showing the Arduino, stepper driver, motor power supply, motor connections, and STEP/DIR/ENABLE signals. The wiring will be based on your exact driver model and pinout rather than assuming a generic connection. One detail I will account for is the 60° position relative to the selected microstepping setting, so the commanded motion is calculated consistently. Deliverables: • Clean, commented .ino source • Adjustable motion parameters • Wiring schematic (PNG/PDF) • Clear connection labels and setup notes I can keep the implementation simple and easy to modify later.
