Abstract

The Raspberry Pi is a credit card sized single-board computer developed in UK by Raspberry Pi foundation with the intention of promoting the teaching of basic computer science in school. Now a days none of the tablets that are available in the market are of Linux OS. In this paper we showcase our attempt at building a low cost stand-alone device called Pi-pad which is very much helpful for educational purpose using the Raspberry Pi as its brain with Bluetooth for connecting peripherals and communicating with local devices like Wi-Fi, keyboard and mouse. It has a touch screen display providing a user interface. The Raspberry Pi Tablet is controlled by a modified version of Debain Linux called Raspbian Wheezy OS optimized for the ARM architecture. The display contains a graphical interface which provides various fields for data entry via onscreen keyboard. Also, in this paper we use Linux commands and python programming for operating and interfacing the hardware. Keywords—Raspberry pi; Linux OS; Python; Wi-fi; ARM; Raspbian; Touchscreen. __________________________________________________*****_______________________________________________
