Many houses and offices use nameplates at their property gates. Nameplates have gained huge popularity and people have been trying new and creative nameplate designs for their beloved properties. But Nameplates have a limited size and can only show limited text.
Well we here take nameplates to a whole new level by making digital nameplates, that not only display family/office name but also welcome guests when they arrive. The digital nameplate offers following features:
- Display Family/ Office Name Digitally
- Display All Family Member Names as it is a Scrolling Display
- Display “We are Out and Will be Returning at
- Detect and Welcome Guests with Welcome Message
The system makes use of an Atmega 328 Microcontroller along with ultrasonic sensor, LED display board, buzzer, buttons for operation along with some basic electronics components and PCB Board to develop the system.
The controller has the input message to be displayed on LED board stored in it. The message could be the Family or office name. This could also contain the names of family members in the family or the company tagline along with company name. The message is with name is showing as scrolling display on the system. This allows a bright moving LED nameplate outside the house or office. The system also consists of an ultrasonic sensor integrated to it.
The ultrasonic sensor transmits ultrasonic frequency which does not return to it unless some object stands in 1 meter proximity of it. As soon as a guest arrives and stands in front of it, the ultrasonic waves are reflected from the user and received by sensor.
This trigger on sensor is detected by the microcontroller. The microcontroller now displays the welcome message stored in it. The message may be message like “Welcome to
