Abstract

This study discusses the process of making a wind tunnel airspeed control device using arduino as the main component of the controller unit. Wind tunnel testing is carried out at varying air speeds as needed in order to obtain optimal results. The fan motor as an air flow generator is not equipped with an air speed controller. The purpose of this research is to make a tool that can control wind tunnel airspeed according to the testing needs. This research was conducted using the research and development method. The power supply voltage output is set at 11.19 Volts as the arduino voltage source and for other components such as LCD displays, servo motors, relay modules and anemometer sensors supplied from the Arduino mainboard plus and arranged in parallel with the power supply source reduced using a stepdown to 5.069 Volts.
