Arduino UNO y mODULO Bluetooth (Problema funcionamiento)

hola, tengo un problema con el funcionamiento de un autito controlado con el celular. el auto tiene 1 motor, un servo(dirección) y un led.  el código que tengo dice q cuando reciba el numero 4 en el serial doblara hacia la derecha, espera 150 milisegundos y después vuelve la posición inicial. cuando lo pruebo con el serial de la computadora, osea, el monitor serial funciona correctamente. pero cuando lo pruebo con el celular conectado con el bluetooth gira y se queda ahí hasta que llegue otra señal al serial. por ejemplo hago q gire la izquierda, gira pero se queda ahí. luego aprieto el de adelante o el led y solo ahi, el servo, vuelve la posición inicial. amigo, puedo ayudarte, pero tu sketch casi no tiene comentarios. si quieres que alguien más te pueda ayudar deberías ponerle comentarios para tener una idea mas clara de lo que has hecho.

arduino modbus

salve, sto affrontando il tema modus tcp su arduino. ho trovato una libreria, msgmodbus http://myarduinoprojects.com/modbus.html, che sembra funzionare egregiamente come master e slave. ora, ho impostato il mio arduino come modus slave, metre come master uso un simulatore da pc. il simulatore recupera dati scritti sul registro holding input senza problemi. la mia domanda è: come si può far si che il master invii allo slave un valore? la teoria dice che si può ma in pratica non riesco. nessuno ha affrontato il problema? se si come? posso utilizzare anche altre librerie, non ho problemi basta che siano su protocollo tcp grazie buona sera, essendo il tuo primo post, nel rispetto del regolamento ( … punto 13, primo capoverso ), ti chiedo cortesemente di presentarti qui ( spiegando bene quali conoscenze hai di elettronica e di programmazione ... possibilmente evitando di scrivere solo una riga di saluto ) e di leggere con molta attenzione il su citato r...

G4とG5のカラーについて

初歩的な質問ですみません。よろしくお願いします。 今までmacg4でillustrator8.0 photoshop5.0を使用していて 最近、macg5を導入したのでillustratorcs2 photoshopcs2も使い始めたのですが、 カラープリンタでG4の出力と、G5の出力の色が一致しません。 illustratorcs2のカラー設定は、「プリプレス用-日本2」にしています。 illustratorは、8.0 cs2共にプリント設定の「print server series」の「cmyk色補正」にチェックを入れて、 cmykシミュレーションを「雑誌広告基準カラー」にしています。 photoshop画像は、epsでillustratorに貼り付けて出力しています。 他の設定で変更している部分がないので、色の違いの原因がつかめません。 このような時、どういった部分を変更していけば良いかお教えください。 よろしくお願いします。 illustratorで作成した色が違いますか? それとも、photoshopでしょうか? photoshopのカラー設定はどのようにしているのでしょうか? epsでも、プロファイルは埋め込めますよね? でも、illustrator 8のときと、illustrator cs2では、扱い方が違っているかもしれません。 illustrator csと、cs2もちょっと違っていたりするようなので。 illustrator 8とphotoshop 5は、ずいぶん古いので、カラーマネジメントの内部の考え方が違ってきているのでは?と思います。 合わせるのは難しいのではないかと思われるのですが。 Photoshop Album SE (Japan) でのその他のディスカッション adobe

Controllo Connessione Bluetooth

ciao tutti. mi chiedevo se esiste un modo per far controllare all' arduino la connessione con il bluetooth collegato su di esso. mi spiego meglio, vorrei fare in modo che se per svariati motivi il bluetooth collegato sull'arduino dovesse interrompersi mi si deve attivare un segnale  con l'accensione di un led. se colleghi il pin state del modulo bluetooth (quale?) ad un ingresso digitale, quello va high quando è connesso ad un device, quindi ti basta controllare periodicamente (non farlo tutto nel loop magari metti un timer e controlli ogni 5-10 secondi). e' questo che intendevi?
