Hi! I noticed you've selected Arduino with Nema 17 steppers, which works for a proof-of-concept, but you'll need A4988 or DRV8825 stepper drivers (Arduino can't source the 1-2A per coil directly) plus a separate 12V/3A power supply since the motors operate at a different voltage than your logic circuit. If you're planning to scale beyond a single axis or want WiFi control later, I'd recommend starting with ESP32 instead—same Arduino IDE compatibility, but 240MHz processing and built-in connectivity for future expansion. Here's how I'd approach your system: **Phase 1** - Component selection and breadboard validation (verify your Nema 17 torque meets load requirements, select appropriate drivers with current limiting). **Phase 2** - Design the control schematic with proper power isolation between motor supply and logic, including flyback protection diodes. **Phase 3** - Firmware development using a state machine architecture for your three modes (switch positions + pot control), with AccelStepper for smooth acceleration profiles to prevent missed steps. **Phase 4** - Integration testing focused on edge cases like rapid mode switching and simultaneous input changes. we can discuss it more in detail in chat. Thanks Regards

@Feriver

Hello, I understand you need an Arduino-based robotics prototype controlling a NEMA 17 stepper motor with dual input modes: fixed-angle rotation (90°, 180°, 270°, 360°) via a momentary switch, and variable rotation via a potentiometer, selectable using a toggle switch. The system must ensure precise motor control, clean switching logic, and reliable execution suitable for robotics prototyping and experimentation. My approach will implement structured Arduino firmware using a reliable motor driver (A4988 or DRV8825) with accurate step and direction control. I will design logic to switch safely between discrete rotation mode and potentiometer-controlled rotation, ensuring smooth motion and precise angle mapping. I will also provide a clear circuit diagram, explain component connections, and guide you on using Arduino IDE or PlatformIO for efficient sketch development and testing. Deliverables include fully commented Arduino code, circuit schematic, wiring instructions, and testing guidance. The prototype will be stable, easy to modify, and ready for robotics integration. I will also assist you in understanding the system so you can extend it independently. Client Clarification Questions Which motor driver are you using (A4988, DRV8825, or another)? Which Arduino board model will be used (Uno, Mega, Nano, etc.)? Thanks, Asif.

@yaroslavmark

✅Okay, I got what you want exactly. I am a robotics prototyping engineer with over 10 years of experience, providing Arduino-based embedded development, stepper motor control systems, and hands-on electronics integration. In my opinion, the cleanest way to approach this is to structure the sketch around a simple state machine that switches input control between the momentary button and potentiometer via a toggle switch, while using an AccelStepper-based control layer for smooth, precise angle positioning. I would calculate exact step counts per degree for your specific Nema 17 configuration and implement debounce logic plus acceleration control so movements to 90°, 180°, 270°, and 360° feel intentional and repeatable rather than abrupt. This project is very similar to my previous works. I recently built a rotary indexing platform using an Arduino Uno and DRV8825 driver where I programmed 12 indexed positions with ±0.2° repeatability, plus dual input modes (manual dial and push-button trigger). In another prototype, I integrated three Nema 17 motors with selectable input logic and calibrated microstepping at 1/16 resolution to achieve consistent torque and smooth transitions under varying loads. Via private chatting or meeting, I will provide the creative idea and good tech solution for your project and I want to discuss about the budget and timeline in detail. Best regards. Yaroslav

@tetianam8

⭐⭐⭐⭐⭐ I can help you build this Arduino stepper prototype cleanly and predictably. For a NEMA 17 you’ll use a driver (A4988/DRV8825/TMC series), and the sketch will support two modes via a toggle switch: Mode A (momentary button): each press advances the motor to 90° → 180° → 270° → 360° (then repeats). Mode B (potentiometer): knob selects the target rotation (mapped to the same angle set, or we can make it continuous if you prefer). I’ll write it non-blocking (so it stays responsive), include proper button debouncing, and make it easy to change steps/rev and microstepping for your specific driver. Milestones: Confirm driver type + motor steps + microstep setting Wiring diagram (toggle, button, pot, driver pins) Arduino sketch with comments + quick test procedure Tune motion (speed/accel) for smooth operation Software: I’ll recommend Arduino IDE for simplicity, or PlatformIO if you want a cleaner workflow. Quick question: which driver board are you using (A4988/DRV8825/TMC)?
