A gamer’s motion, a programmer’s voice, a DJ’s instrument and a designer’s brush; a single keyboard plays multiple roles in a computer. Similar is the case of a computer mouse that can make clicks to move a card in solitaire or open a web browser. For a computer buff of the current times, imagining a computer without these input accessories is impossible. Hence, it is utterly needed for these gadgets to tightly connect to the computer 24 x 7. Enabling a good connection are the PS2 connectors that have been in trend since a long time. Invented by IBM PCs, PS2 or personal station 2 connectors have reigned as sole connectors for keyboards and mouse for a long time. Easy manufacturing, ability to link tightly and fewer chances for connection error make it interesting to explore the insides of these connectors.
Typing Assistant based on 8051 microcontroller
Just as a PC software, that are being used in PCs to increase the typing skill and speed in a computer keyboard, this device has been developed to do the same job but without any PC. The device has a PS/2 keyboard port to connect a computer PS/2 keyboard (not an USB keyboard) and a LCD screen to display. When the circuit is assembled and programmed, a PS/2 keyboard has to be connected at the PS/2 socket provided in the device and it then serves as a portable TYPING ENHANCER. It needs only a 5V power supply and nothing else. It has no connection with PC.
