Raspberry Pi stepper motor gimbal

thingiverse

Raspberry Pi API project that offers two video streaming options and stepper motor movement with a full 360° rotation. **DEMO VIDEO:** https://www.youtube.com/watch?v=GQbLwBo25KM The main API endpoints for this project are focused on camera movement and video stream. **/api/stepper** with query parameters: - move = up - move = down - move = right - move = left - move = stop **/stream.mjpg** This endpoint is used to enable video streaming. We also have another option for video streaming that provides faster and better video quality. The stream_server (https://github.com/ManolescuSebastian/Raspberry-Camera-Gimbal/tree/master/CameraGimbal/stream_server) is a standalone server that requires to run on a different port. More information can be found here: https://picamera.readthedocs.io/en/release-1.10/recipes1.html ### How to start the project To begin, we need to add a base URL in MainApp.py (or CameraStream.py if you are using the streaming server). To find out your Raspberry Pi IP, open a terminal and type ifconfig (192.168.1.X). Add the Raspberry Pi IP to MainApp.py in the last code line (e.g., app.run(debug=True, port=5050, host='192.168.1.X', threaded=True)) or/and if you are using CameraStream.py add it to address = ('192.168.1.X', 5020). **Note:** You can choose any port you want; 5050 and 5020 were personal choices. After completing the above steps, open a terminal and type python MainApp.py or/and python CameraStream.py. ### Libraries required to run this project Flask (https://pypi.org/project/Flask/) ### Pinout connection Raspberry pi | ULN2003 Driver Board (1) ------------ | ------------- GPIO21 | IN1 GPIO20 | IN2 GPIO16 | IN3 GPIO12 | IN4 GND | GND 5V | 5V Raspberry pi | ULN2003 Driver Board (2) ------------ | ------------- GPIO26 | IN1 GPIO19 | IN2 GPIO13 | IN3 GPIO06 | IN4 GND | GND 5V | 5V
