Abstract

In general, security safe box is currently still using key combination that has some drawbacks. One of the weaknesses is the risk of lossing of the keys and forgetting the lock codes that impact at users of not being able to operate the safe box. Therefore, the researcher is designing a tool that is more practical and safe that can replace the key of security safe box. In the research,  the researcher uses the method of fingerprint and a PIN by  designing a circuit input tool using the output fingerprint sensor and keypad. For the series of processor,the researcher applies the Arduino microcontroller Uno R3 while for series output the researcher applies  three output circuit such as LCD, Buzzer, and Selenoids. Security tool safe box can only be operated by entering PIN and fingerprint which have been registered. Hence, the users do not need to save an object to operate the safe box. Based on the results of testing, this tool is able to open the safe box by inputting 5 registered  ID interchangeably as much as 25 times. The Solenoids then are able to operate when they are given voltage > 9, 5V 350 mA to 12V 800 mA.
