The PiAutoStage captures images by integrating Python, Raspberry Pi HQ Camera, and Arduino technology. The system is controlled by a central Raspberry Pi computer running a Python script.

The Python script is the main control code for the PiAutoStage. The Python script sends stage coordinates to the Arduino Microcontroller which then instructs the servos to move the sample into position. The Python script then captures an image with the HQ Camera. This process repeats until all the sample is imaged. See the GitHub repository for the script.

Our Arduino sketch (script) interprets instructions from the Python code then delivers coordinates to the servo motors. An important feature of our script is a GoCode that prevents the servos from moving unless specific instructions are given. This prevents unintended movement during startup that may damage the stage or microscope. See the GitHub repository for the script.
