Students of the Faculty of Engineering Department of Electronics Engineering, Yogyakarta State University developed the typewriter wide use of printer used.

"Typewriters it helps people make a wide range sighted easily, without having to memorize every letter motif. Yet another advantage is the relatively affordable price of about Rp 700,000 per unit," said Zaenal in Yogyakarta, Sunday (12/30/2012).

According to him all work orders on the typewriter found on the keyboard. Some of the major keys such as F9 function pulls the paper down and the F10 key to pull the paper in the opposite direction.

F11 and F12 function keys to move the solenoid to the left and to the right to get the right position on the paper. "To stop the command from the buttons we can use the space, while the lower solenoid one line we can use the F8 key," he said.

He said at the typewriter each key letters, numbers, and punctuation are pressed will produce 'output' in the form of the movement of two stepper motors and solenoid so will result in wide motif as described in the paper.

"Typewriters wide ATmega16 microcontroller-based electronics that consists of three parts," he said.

The first part consists of a sturdy keyboard ps2 votre specifications. Keyboard generates serial data on each key is pressed. The second part is the minimum system requirements. In the series there is an ATmega16 microcontroller as controller working all parts of typewriter.

The third part is the mechanical output of three contained two stepper motors and a solenoid, stepper motors first serves to pull the paper, while the second stepper motor function solenoids to shift positions.

"Development of wide mesik type it under the guidance of professors Education Electronics Engineering Faculty of Engineering UNY Putu Sudira," he said.
