In this Part we going see step by step how to making android apk. Ghassen Ben Taher .© Android: New Project Open Android Studio and create a new Project:  File > New Project. A pop up Windows will appear. Change the Application Name and Company Name:   Click next to choose the target of the application. Click next and choose a Blank Activity.

For  Arduino  you will need :  Arduino Uno LM35 ( or other sensor) Resistors 300 Ω (3x) Jumpers Bluetooth Module (HC-06/other) Android phone  SSP Bluetooth Apk (unWiref Lite ) C programming skills And for Android  before start coding you must : Download Android studio IDE and update Java ( or Eclipse IDE , it’s almost the same) Jaa and C programming skills will help This tutorial will not expalin Java programming The apl will send commands to turn on/off the led and control the brightness. See you on part 2 of this tutorial Ghassen ben Taher .©
