Introduction
The common way to advertise is to make banners, hoardings, paintings, etc. But now a day’s digital display is also getting popular to display advertisement, because of their durability and customization feature. So, in this tutorial, we will make a wireless noticeboard. Here we are using only one P10 display but you can build any size of the display for your advertisement board.
In one of our tutorials, we interfaced the P10 display with Arduino. You can follow this tutorial on how to interface with the P10 display. And jump into this tutorial to build your own Wireless advertisement board.
This is an electronic wireless display board. Using Arduino, HC-05, and P10/DMD Display.
About P10 Display
P10 is a 32×16 LED display with a total of 512 LED’s and the easiest display to interface with any of the microcontroller having SPI communication. This display is best for out door displaying. This display can be reconfigure to any size. This can be used a advertising boards in mall, railway stations, and in any public place.
P10 display pin descriptions:
- Pin1 (OE) – is the enable pin and it is used to control the brightness of the panel.
- Pin2 (A) and Pin3 (B) are the two selection line to select from multiple rows.
- Pin8 (CLK), Pin10 (SCLK), and Pin12 (DATA): are the control and data pins of the shift register.
- P10 display uses SPI communication to communicate with Arduino. So, in our code, we will use the SPI library.
