In this work, a spinner apparatus was mounted with some characteristics, as: low cost, easy operation, compact size, easy adaptation into the little glove box systems, no vacuum pump and low maintenance. Firstly, three different fans wereanalyzed to be used in thespinner apparatus. Then, the Arduino electronic circuit was analyzed and programmed to control the rotation speed using a pulse width modulation (PWM) and steps of acceleration with the signal distortion (caused by pulse width modulation) of thefan intern tachometer. After, the interface between the user and spinner apparatus was performed with information about: navigation through the menus; input of process parameters as rotation speed; rotation time and calibration menu. Successive depositions of organic thin films to assembly of OLED deviceswere used with the spinner apparatus. The experiment compared ITO (indium tin oxide) thin filmanodes with sheet resistances of 8 and 12 ?/? supplied by different manufacturersin the structure of the OLEDs.I-V curves of OLED devices showed that the ITO/glass of 12 ?/? presented better results with low variabilityand highest current values. All OLED devices presented some luminance showing the efficiency of spinner apparatus.
