# How-to's and tutorials

## Tutorials

Embarrassingly (and potentially dangerously) amateuristic, but possibly useful.- My introduction to statistics via simulation programming; also presents an argument for a valid role of NHST in experimental research.
- Programming online tasks in barebones JavaScript.
- Programming Tasks for Psychological Experiments using Presentation.
- Data Wrangling in Social Science and Psychophysiology using Matlab.
- Sending triggers and event markers via USB, how to get TTL pulses and other marker-bits out of a USB port.
- Homebrew Heart Rate Sensor Measurement via Arduino.

Note: there's another "book" floating around that's actually just an expensive version of my thesis, which is freely available here as a PDF.
