In a previous post I showed how to connect an app inventor Android app to a Bluetooth module connected to an Arduino to control an LED. See Turning a LED on and off with an Arduino, a HC-06 and Android A few people have asked how to make it so that the app auto-connects to the...
2. Use phone to turn on and off lights in the house. Key Points Analysis 1. Let the app send signals that can control the servo. In the previous section, we made an app that turns on and off of the LED. It is performed by sending data A and B. Here we can use the app made...
