/** * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters. Each * repeater and gateway builds a routing tables in EEPROM which keeps track of the * network topology allowing messages to be routed to nodes. * * Created by Henrik Ekblad * Copyright (C) 2013-2015 Sensnology AB * Full contributor list: https://github.com/mysensors/Arduino/graphs/contributors * * Documentation: http://www.mysensors.org * Support Forum: http://forum.mysensors.org * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * version 2 as published by the Free Software Foundation. * ******************************* * * DESCRIPTION * * Simple binary switch example * Connect button or door/window reed switch between * digitial I/O pin 3 (BUTTON_PIN below) and GND. * http://www.mysensors.org/build/binary */ // Enable debug prints to serial monitor #define MY_DEBUG // Enable and select radio type attached #define MY_RADIO_RF24 //#define MY_RADIO_RFM69 #include #include #define CHILD_ID 3 #define BUTTON_PIN 3 // Arduino Digital I/O pin for button/reed switch Bounce debouncer = Bounce(); int oldValue=-1; // Change to V_LIGHT if you use S_LIGHT in presentation below MyMessage msg(CHILD_ID,V_TRIPPED); void setup() { // Setup the button pinMode(BUTTON_PIN,OUTPUT); // Activate internal pull-up digitalWrite(BUTTON_PIN,LOW); // After setting up the button, setup debouncer debouncer.attach(BUTTON_PIN); debouncer.interval(5); } void presentation() { // Register binary input sensor to gw (they will be created as child devices) // You can use S_DOOR, S_MOTION or S_LIGHT here depending on your usage. // If S_LIGHT is used, remember to update variable type you send in.

Here's one resource: https://github.com/thedalles77/USB_Laptop_Keyboard_Controller

There's a way to convert a Thinkpad keyboard to a standalone USB keyboard (with working Trackpoint), but requires electronics knowledge and other relevant stuff: https://github.com/thedalles77/USB_Laptop_Keyboard_Controller
