How to Make an Acceleration Switch for Parabolic Flight Experiments (No. 1) A lecture for a Beginner to Make a Microcomputer-Controlled, Electronic Device

Abstract

The lecture introduces how to make a microcomputer-controlled, electronic device for a beginner. A series of lectures provides not only how to measure a physical property with an electronic sensor, convert it to a digit (analog digital conversion), switch on and off an electronic circuit with FET (Field Effect Transistor), and control those with a microcomputer but also practical know-how to design an actual electronic circuit, choose appropriate electronic parts, and mount those to a PCB (printed-circuit board), with explaining how to make “an acceleration switch”. The switch can automatically turn on and off a connected device according to an acceleration level measured with an acceleration sensor and contribute to parabolic flight experiments through size reduction of an apparatus, less operation, and precise control of the experiments.
