GSM Based Alphanumeric Scrolling Display System
This technical paper explains "GSM based Alphanumeric Scrolling Display System" which can be widely used for displaying notices in colleges, advertisement in stock market, public place on digital notice board by sending messages in form of SMS through mobile.
Raj Hakani (2014) worked on GSM based alphanumeric scrolling display system using PIC 16F877A microcontroller interface with GSM modem via MAX232 level convertor. Hardware also include DS1307 real time clock, alphanumerical panel and multiple 16×2 character LCD displays and microcontroller coding was done using Embedded C and MpLab.
The wireless scrolling message display board operates based on the instruction stored in the atmega328p microcontroller memory. The microcontroller and the display unit are powered from the power supply through separate LM 7805 regulator as shown in the system block diagram of Figure 1.The interfacing
LED Scrolling Display Board Circuit Using AVR Microcontroller
LED Scrolling Display Board. This article explains the steps involved in designing a scrolling message LED Display. The following features of the display are explained in the article. Framing Alpha-Numeric characters and special characters; Multiplexing the matrices; Serial mode of data distribution using shift registers; Static text display
A microprocessor is a multipurpose, programmed clock driven register based system which takes the input in binary process (arithmetic, logical) and gives the output. The 8086 is the first 16-bit microprocessor released by Intel which can execute 2.5 million instructions per second. It has a 20-bit address bus.
Using a PIC Microcontroller to input, store, control and display the data for the message characters on a dot matrix. The figure below is the Building blocks diagram of a Moving Message Display System. Figure. 1: Block diagram of a moving message display system
