手始めに、Arduino IDE v.1.8.3の
［スケッチの例］－［09.USB］－［Keyboard］－［KeyboardSerial］から。
シリアルモニタから文字を送信すると、 USB Keyboardとして文字を返しますが、
例えば「A」送信で、キーコードの次「B」を返すというシンプルなスケッチです。
使ったスケッチは、これです。
Arduino Leonardo、Micro、Duo用とあります。
USB-SerialとUSB-Keyboard同時は、ATmega32u4じゃないとできないのです。
これは、外部回路は不要です。
＊＊＊＊＊ /* Keyboard test For the Arduino Leonardo, Micro or Due Reads a byte from the serial port, sends a keystroke back. The sent keystroke is one higher than what's received, e.g. if you send a, you get b, send A you get B, and so forth.

一応、スケッチをコピペしておきます。
これもArduino Leonardo、Micro、Duo用とあります。
スケッチは、十分理解できておりませんが、動きは予想できるので、
いきなりやってみることにします。
＊＊＊＊＊ /* JoystickMouseControl Controls the mouse from a joystick on an Arduino Leonardo, Micro or Due. Uses a pushbutton to turn on and off mouse control, and a second pushbutton to click the left mouse button Hardware: * 2-axis joystick connected to pins A0 and A1 * pushbuttons connected to pin D2 and D3 The mouse movement is always relative. This sketch reads two analog inputs that range from 0 to 1023 (or less on either end) and translates them into ranges of -6 to 6. The sketch assumes that the joystick resting values are around the middle of the range, but that they vary within a threshold. WARNING: When you use the Mouse.move() command, the Arduino takes over your mouse! Make sure you have control before you use the command. This sketch includes a pushbutton to toggle the mouse control state, so you can turn on and off mouse control. created 15 Sept 2011 updated 28 Mar 2012 by Tom Igoe this code is in the public domain */ #include "Mouse.h" // set pin numbers for switch, joystick axes, and LED: const int switchPin = 2; // switch to turn on and off mouse control const int mouseButton = 3; // input pin for the mouse pushButton const int xAxis = A0; // joystick X axis const int yAxis = A1; // joystick Y axis const int ledPin = 5; // Mouse control LED // parameters for reading the joystick: int range = 12; // output range of X or Y movement int responseDelay = 5; // response delay of the mouse, in ms int threshold = range / 4; // resting threshold int center = range / 2; // resting position value boolean mouseIsActive = false; // whether or not to control the mouse int lastSwitchState = LOW; // previous switch state void setup() { pinMode(switchPin, INPUT); // the switch pin pinMode(ledPin, OUTPUT); // the LED pin // take control of the mouse: Mouse.begin(); } void loop() { // read the switch: int switchState = digitalRead(switchPin); // if it's changed and it's high, toggle the mouse state: if (switchState != lastSwitchState) { if (switchState == HIGH) { mouseIsActive = !mouseIsActive; // turn on LED to indicate mouse state: digitalWrite(ledPin, mouseIsActive); } } // save switch state for next comparison: lastSwitchState = switchState; // read and scale the two axes: int xReading = readAxis(A0); int yReading = readAxis(A1); // if the mouse control state is active, move the mouse: if (mouseIsActive) { Mouse.move(xReading, yReading, 0); } // read the mouse button and click or not click: // if the mouse button is pressed: if (digitalRead(mouseButton) == HIGH) { // if the mouse is not pressed, press it: if (!Mouse.isPressed(MOUSE_LEFT)) { Mouse.press(MOUSE_LEFT); } } // else the mouse button is not pressed: else { // if the mouse is pressed, release it: if (Mouse.isPressed(MOUSE_LEFT)) { Mouse.release(MOUSE_LEFT); } } delay(responseDelay); } /* reads an axis (0 or 1 for x or y) and scales the analog input range to a range from 0 to <range> */ int readAxis(int thisAxis) { // read the analog input: int reading = analogRead(thisAxis); // map the reading from the analog input range to the output range: reading = map(reading, 0, 1023, 0, range); // if the output reading is outside from the // rest position threshold, use it: int distance = reading - center; if (abs(distance) < threshold) { distance = 0; } // return the distance for this axis: return distance; }

まずは、スケッチを書き込みます。配線は後です。
COM14が消え、COM11が現れます。
書き込み時は、常に「Arduino Micro bootloader（COM11）」が出現します。
書き込みが終わるとすぐに消えます。
そのSparkfunサイトからスケッチをコピペしてきますm(_ _)m
