Visual depiction of a compact wireless keyboard. A wireless keyboard is a computer keyboard that allows the user to communicate with computers, tablets, or laptops with the help of radio frequency (RF), such as WiFi and Bluetooth or with infrared (IR) technology. Wireless keyboards in the current market are commonly accompanied by a wireless mouse.

[83] [84] The Arduinophone [84] (touchscreen) and the MIT DIY Cellphone (segmented display) [85] [86] both use the Arduino open-hardware single-board computer, with added components. Circuitmess Ringo (previously MakerPhone) is another DIY Arduino phone with open source firmware [87] and available schematics, [88] focusing on education.
Without a matrix circuit, a 61-key keyboard for a digital piano or a computer keyboard might require 62 wires to connect (one for each key, and a ground)—an awkwardly thick bundle of wiring. With a matrix circuit, any of 61 keys can be determined with only 16 wires.
In 1975, the first general purpose home automation network technology, X10, was developed. It is a communication protocol for electronic devices. It primarily uses electric power transmission wiring for signalling and control, where the signals involve brief radio frequency bursts of digital data, and remains the most widely available.
Some hackers also use wireless keylogger sniffers to collect packets of data being transferred from a wireless keyboard and its receiver, and then they crack the encryption key being used to secure wireless communications between the two devices. Anti-spyware applications are able to detect many keyloggers and remove them. Responsible vendors ...
A Kickstart edition can be downloaded for free from TI or IAR; it is limited to 8 KB of C/C++ code in the compiler and debugger (assembly language programs of any size can be developed and debugged with this free toolchain). TI also combines a version of its own compiler and tools with its Eclipse-based Code Composer Studio IDE (CCS). It sells ...
