Advertising is the most common and important thing for a product, service, or any feature you want to sell. 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. You can set text, display images and even you can play a video on the display. These boards are a little costly but due to their features, it's gaining a place in the market. In this tutorial, we will interface a red 32x16 dot matrix display (DMD).

The size of the P10 display is 6 inches in height and 11 inches in width. The display contains a total of 512 LEDs. LED color varies according to your purchase. Here I am using a RED DMD display.

Using P10 display you can build any size of display for your advertisement board. These display boards are IP65 waterproof.

Specification of P10 display:

  • Brightness  - up to 5000
  • Maximum power consumption - 20watts
  • IP65 waterproof.
  • Pixel configuration - 10mm

P10 display pin descriptions:

  • Pin 1(OE)- is the enable pin and 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 pins of the shift register.

Hardware Requirements:

  • Arduino UNO board
  • P10 display
  • Connecting wires

Software Requirements:

  • Arduino IDE (You can download it from HERE) 
  • DMD Library (Download it HERE)
  • TimerOne Library ( Download it HERE)
