Arduino Leonardo は、ほとんどが Arduino Uno と同じ構成で使えて、さらにパソコンに接続した状態で、マウスやキーボードの代わりにもなる便利なボードです。つまり、他のスイッチやハードウェアをつけなくても単体で遊べる範囲が多いのが特徴です。 Arduino を紹介した多くのページでは、Arduino を USBに接続すると自動的にドライバの組み込みがされるように書かれてますが、2/12にダウンロードしたIDE環境「Arduino 1.0.5-R2」+ Windows 7 の場合は、そうではなかったので、少し補足しておきます。参考になる人がいれば幸いです。 1.Windows 7 でのドライバのセットアップ方法 1.1 「Arduino 1.0.5」を展開したフォルダの「drivers」フォルダにある「Old_Arduino_Drivers.zip」を展開して、中にある「Arduino Leonardo.inf」を「drivers」フォルダの中に書き出します。 1.2 Windows 7 が 32bit版なら、dpinst-x86.exe を実行し、ドライバをインストールします。 64bit版なら、dpinst-amd64.exe を実行します。 1.3 そののちに Arduino Leonardo を USBに接続すると「Arduino Leonardo」がきちんと認識されるようになります。 2.ボード単体で遊べるスケッチ (サンプルコード) 「01.Basics」>「Blink」「Fade」で、ボード上のLED点灯を試せます。 「04.Communifation」>「PhysicalPixel」は、IDEの「ツール」>「シリアルモニタ」を開いて、H, Lという文字を送信することで LEDのオフ・オンをコントロールするデモ。 「05.Keyboard」>「Keyboard」>「KeyboardMessage」も同様にシリアルモニタ上で入力した文字を書き換えるデモ。 プログラムコードはシンプルなので、プログラムに振れたことがある人なら、誰でも簡単に動きを理解することができるのではないでしょうか。

This board is an excellent choice for custom projects that need direct USB communication. The ATmega32U4 chip makes it stand out because it can act as a keyboard or mouse without extra libraries, which opens up a lot of creative possibilities. With 20 digital I/O pins, 7 PWM outputs, and multiple analog inputs, there is plenty of flexibility for sensors, LEDs, and control devices. The headers are sturdy and make prototyping easy on a breadboard or with jumper wires. Running at 16MHz, it is fast enough for most hobby and DIY applications. Setup with the Arduino IDE was seamless and sketches upload quickly over USB. The board has been reliable during testing, and the small size makes it easy to embed into projects. A great microcontroller for makers who want more functionality than a basic Uno while still keeping full compatibility with the Arduino ecosystem

Ho scelto il Leonardo come primo Arduino quasi per caso, dato che non avevo esperienza con la piattaforma ed alla fine si è rivelato adatto ai miei scopi, perfino più del "tradizionale" UNO. + seconda porta seriale a disposizione; + i piedini digitali non sono connessi in parallelo al connettore ISC quindi restano più piedini disponibili quando si usano gli shield; - usa il cavetto USB micro che non è molto diffuso; - la connessione USB è un po' instabile per le continue sconnnessioni e riconnessioni; - il chip è saldato sulla scheda per cui non si potrà usare per programmare un chip da montare poi su uno stampato standalone, che potrebbe risultare comodo per gli utenti avanzati; - ho avuto problemi nell'utilizzo di un ethernet shield w5100 non originale, devo ancora capire se dipende dal Leonardo o dallo shield difettoso.

Das Arduino Leonardo mit Headers bietet die gewohnt hohe Arduino-Qualität und ist ein sehr gutes Produkt, besonders für Projekte, die Tastatureingaben am Computer simulieren sollen. Ich nutze es genau für diesen Zweck, und die Umsetzung über das USB-Kabel ist unkompliziert und benutzerfreundlich. Dank der integrierten USB-Schnittstelle funktioniert das Board hervorragend, um Tastatureingaben, Mausbewegungen oder andere HID-Anwendungen zu steuern. Für alle, die an interaktiven Projekten arbeiten, bei denen der Computer direkt gesteuert werden soll, ist das Arduino Leonardo eine großartige Wahl!
