PICA: Python Instrument Control & Automation
A suite of Python scripts using PyVISA to control and automate laboratory instruments for materials science and physics research.
About This Project
This collection provides practical, ready-to-use Python scripts for automating common electrical and thermal characterization experiments. Each folder is dedicated to a specific instrument or measurement setup, containing the necessary control logic and GUI.
A collection of official instrument manuals is available in the _assets/Manuals directory for reference.
