To design a microcontroller based moving display is not a simple project. With the help of this project we put any message in the microcontroller and microcontroller display this data on the led’s.
This project is not possible without the help of microprocessor or controller. This project is only possible with the help of microcontroller.
When we want to write a M in the display board then it is not possible to display the M directly. We convert the M into the digital code. So firstly we want to decide , what’s the height of M , width of M . so in this project we use matrix of 5 by 7 in this project. On this 5 by 7 we design the M by itself and then convert this value into digital code.
