Camera Slider controlled by bluetooth

This design is based on the work of https://www.thingiverse.com/thing:1041408,\n\nto get all the parts, please visit the link and download the designs, while I have modified three key components to suit my needs.\n\nthe camera mount,\n\nthe Rail Foot,\n\nfoot extension.\n\nStep 1,\n\nI began by examining the design in Rhinoceros to understand how all the parts work together. This process is quite straightforward; simply import all the files downloaded from thingiverse and assemble them to resemble a finished camera slider. It's similar to playing with Legos, but in a 3D program.\n\nStep 2,\n\nOnce you grasp the layout of the design, move on to the next step. You must acquire all the parts, which are listed on this link https://learn.adafruit.com/bluetooth-motorized-camera-slider/overview in the components section. To expedite part procurement, consider using Amazon's one-day shipping option if budget permits. Upon receiving the parts, assemble the Arduino and shield first; this is the most challenging aspect for me. Begin by studying the circuit diagram to familiarize yourself with it https://learn.adafruit.com/bluetooth-motorized-camera-slider/circuit-diagram. Then proceed to the hardware section https://learn.adafruit.com/bluetooth-motorized-camera-slider/hardware, paying close attention to every detail, including the direction of the Bluetooth chip and pin placement. Once you've completed wiring, connect it to the Arduino and stepper motor, ensuring that USB is connected to your computer. Also, verify that VIN jumper is in place; without it, power will not reach the stepper.\n\nStep 3,\n\nNow we move on to the software component, which can be a bit tricky. https://learn.adafruit.com/bluetooth-motorized-camera-slider/software install the Arduino software and ensure you have the required libraries installed: \n• Adafruit Motor Shield V2 Library.\n• Adafruit BluefruitLE nRF51.\n\nVerify that Arduino is selected from Tools>Board >Arduino and the port as well. Once everything is connected, copy the code from the link above,\n Advanced Controller Motor Shield Sketch,\nthen paste it into the Arduino software, verify it, and upload it.\n\nStep 4,\n\nNext, download the Adafruit Bluefruit LE app on your smartphone, open it, and ensure Bluetooth is enabled. The app will detect the Arduino if everything is connected correctly; if not, there may be an issue with wiring. Go to the control section, press the right arrow key, and the stepper motor should rotate step-by-step.\n\nStep 5,\n\nNow connect all components together, refer to this link https://learn.adafruit.com/bluetooth-motorized-camera-slider/assembly. Once connected, adjust the code to suit your Rail length by modifying STEPPER_STEPS; increasing this value will allow the slider to travel farther, while decreasing it will make it shorter. \n\n 1. // Stepper motor config --------------\n 2. #define STEPPER_STEPS 1100 // Length of slider\n 3. #define STEPPER_RPM 2 \n\nI also modified the code to change mode; number 2 now moves to the right slowly, and number 4 moves faster to the right; number 1 moves left slowly, and number 3 moves left faster.\n\ncase '1': if(!moving) {\n motor->step(1750, BACKWARD, MICROSTEP);\n break;\n }\n case '2': if(!moving) {\n motor->step(1750, FORWARD, MICROSTEP );\n break;\n }\n case '3': if(!moving) {\n motor->step(1750, BACKWARD, DOUBLE);\n break;\n }\n case '4': if(!moving) {\n motor->step(1750, FORWARD, DOUBLE);\n break;\n }\n\ngood luck.
