<![CDATA[Abstract: Erratic weather changes cause continuous rain, so clothes that have been washed will take a long time to dry and become damp. The process is carried out in open air and requires quite a large space. The aim of this research is to design an Arduino Uno-based automatic clothes dryer that can dry clothes and determine the dryness level of clothes automatically. The research method used is research and development where the process of developing a clothes dryer system which previously used a heater is now perfected by using a light hair dryer and two fans. The results of testing the tool system begin with the time being set by an Arduino timer and the temperature being set by a humidity sensor.
