Brief Overview of This Arduino Wireless Doorbell Project:
In this project, we are going to build a Wireless Doorbell using Arduino. We will have a button which when pressed will wirelessly play a melody of our choice to indicate someone is at the door. For wireless connectivity, we will use the 433 MHz RF module. In general, the RF module must always be accompanied by a decoder and encoder module, but in place of the decoder and encoder module, we can also use a microcontroller such as Arduino which we are using in this tutorial.
