Workshop on biofilms with Katja Bühler
Workshop Pocket Science Lab (PSLab): Measurements and Robot Controls with Marco Antonio Gutierrez and Mario Behling
Introduction
During this workshop in January, we learned about the PSLab - Pocket Science Lab -, which is an open-source project. A small hardware extension board enables the collection of measurements and data with the phone or PC through different sensors.
PSLab can function as a:
Oscilloscope I Multimeter I Logic Analyzer I Wave Generator I Power Source I Accelerometer I Barometer I Compass I Luxmeter I ...
Sensor experiments
After learning about the functions and possibilities we started experimenting by connecting the PSLab sensors to the PC and giving commands in Python.
coding in Python
We were using the board as an oscilloscope to graphically display varying electrical voltages. For that, we connected two points on the device and changed the script to generate waves with different characteristics.
