If you are also feeling the same trust me it’s as easy as making cup of tea. So without wasting time let’s see How to Control LED from your Voice Command using Arduino and HC-05 Bluetooth module.
So to catch our voice command and process to Arduino board we need something right? To achieve this we have developed an Android App that is IoTBoys freely available on Google Play Store. So what does this IoTBoys App do ? Ok. The purpose of this application is to detect the voice command and pass through Serial Communication HC-05 to the Arduino Board. As we have written sketch below that will take care of all. Once you watch below video you will understand clearly.
