Digital pen with keyboard functionality
Abstract
Proposal for building a wireless digital pen, which can work like a keyboard but more elegantly with the help of gyro sensor and C++ program be used for writing in classrooms, conferences, at presentation or anywhere. This pen contains Gyro sensor which is on a very basic level is used to choose the angle of the advancement of the pen of the 2-axis estimation by then transmit it to microcontroller which is then scrutinized the position and differentiation it and the letter sets which starting at now been set by position with the help of C++ language. By then the microcontroller trades the data to 7-segment display and Bluetooth at the same time and exhibits the letter set or the numerical impetus on the show. Right when the desired letters all together is showed up on the show and the pined for letters all together or number is met, the Bluetooth module accumulate the information and send it to sagacious devices like PC or wireless when push button is pressed
