| Any information on how to create a wireless keyboard using PIC microcontroller?or any information on the design of a wireless keyboard..Im glad also if anyone can share on wireless mouse too using PIC microcontroller..A design on IR maybe a start..thnks guys!ü

I think a good project using ZigBee(Freescale or ChipCon transceivers) and one NanoPower Pic microcontroller 18F series.
Microchip provide a single ZigBee solution with ChipCon transceiver. Then You can only write the code for Your application, without any problem with wireless network protocols!

if you are using AVR and bascom avr compiler you can use the at90s2323 and instructure
getatkeyboard ()
with right configuration (as an example)
then send the character serialy by uC to RF data chip(TRX an RXD) such as arrul chip or other.
on the other hand you receive the data serialy by RF receiver (usually 433.92 MHz)
for more information about RF module go to

| One of the most important thing for wireless mouse and keyboard is the latency time. No one will work with too sloooow mouse and keyboard. So, responce time should be very small for comfortable use. I would suggest to check for ready wireless keyboard/mouse reference designs - there are some available from RF chip producers. For example, check RadioDesk from Chipcon.
