The Arduino Pro Mini is an ATmega168 based microcontroller board. The board comes with built-in arduino bootloader. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. The board can be connected to the PC using…

You can see the notice boards being used specially at offices and public places to display important news and notices. To make the notice boards easy to use and more technical advance, I have used this prototype of wireless notice board where we can display the message by simply sending the message through your cell phone. These display systems are very accurate and easy to control and cheaply available and the most important thing is that they can be operated on low Voltage (Up to 12 Voltage).A GSM module is used here for the wireless notice board to send the information or message to display. The main aim of this project is to save time and provide information urgently on display for the customers.
