Perkembangan pesat kemajuan teknologi komunikasi seluler dan pengurangan biaya memungkinkan untuk menggabungkan teknologi seluler ke dalam sistem mikrokontroler untuk pengontrolan peralatan listrik. Untuk dapat mengendalikan peralatan listrik seperti lampu, kipas atau ac hanya dengan menggunakan perintah suara tanpa perlu bergerak berpindah tempat untuk menyalakan atau mematikan peralatan listrik. Penelitian ini bertujuan untuk mengendalikan peralatan listrik dengan gelombang suara dengan aplikasi android Blueetooth Voice Kontroler. Suara yang kita ucapkan sesuai dengan yang sudah diprogram dalam aplikasi Arduino pada smartphone android akan menyalakan atau mematikan peralatan listrik yang kita tentukan. Berdasarkan hasil pengujian pada prototype sistem kontrol peralatan listrik, bila aplikasi android Arduino Bluetooth Voice Controller diaktifkan dan diucapkan perintah : Kipas ON / Kipas OFF, Nyalakan Lampu / Matikan Lampu, Nyalakan AC / Matikan AC peralatan listrik tersebut akan ON/OFF setelah perintah suara diberikan.The rapid development of cellular communication technology advances and cost reduction made it possible to incorporate cellular technology into microcontroller systems for controlling electrical equipment. To be able to control electrical equipment such as lights, fan or air conditioners only by using voice commands without the need to move from place to place to turn on or turn off electrical equipment. This study aims to control electrical equipment with sound waves with the Bluetooth Voice Controller android application. The sound we speak according to what has been programmed in the Arduino application on an android smartphone will turn on or turn off the electrical equipment that we specify. Based on the test results on the prototype control system for electrical equipment, when the Arduino Bluetooth Voice Controller android application is activated and the command is spoken: Fan ON / Fan OFF, Turn on Lights / Turn off Lights, Turn on AC / Turn off AC the electrical equipment will turn ON /OFF after a voice command is given.Keywords: Android; Bluetooth; Arduino Uno; electrical equipment
Demand of clean and healthy water services in the community
Human need for technology is difficult dammed because there are many facilities that enable people to be able to optimize performance at work every time. Currently mobile handheld electronic devices no longer only have the functionality of the phone or sms but improved to be a medium that can control every electronic device in the house. This study aims to control the temperature and humidity in a room using arduino uno microcontroller that is controlled with android smartphone with wifi media. Test results show that applications on Android smartphones can inform the state of temperature and humidity in a room. Control Room App on Android with Auto, Semi Auto (Cold, Hot and Hot) and Manual (Fans and Heaters) option. Remote control distance on the Android app to Arduino Uno microcontroller is approximately 150 meters, The duration of delay that occurs when Arduino Uno processes the command from Android at 0-80 meters distance is 0.5-1 second and at a distance of 90-150 meters is 2-3 seconds.
Rapid development of technology today has penetrated into various fields. Technology it is present and developing continuously along with the increasing human needs, one of the technologies developed, namely the microcontroller. A microcontroller is a device control on the be used as a main control on a system that is both simple and complex. In the Final project with the title "System Overcurrent Protection Single Phase Using a Microcontroller Atmega 8535". As the main control on the system are made. This system acts as a protection on the electrical system where if the load current has exceeded the limit then the system will decide contact the supply automatically.On the protection system are made, the detection of current using a current transformer to convert the magnitude of the current into a voltage and the magnitude of the voltage will be measured by the microcontroller as a reference for control contacts supply power to the load, the magnitude of the load that is supplied is set using the input set point to the microcontroller if the current detected exceeds the set point of the supply is decided automatically.
