Cum se utilizeaz\u0103 Arduino GSM Shield SIM900<\/span><\/h2>\n

Modulul poate fi alimentat de una din dou\u0103 moduri:<\/span><\/p>\n

1. <\/span>Surs\u0103 de alimentare separat\u0103.
\n<\/span>2. D<\/span>e la Arduino.<\/span><\/p>\n

Pute\u021bi alege sursa de alimentare de la comutatorul DIP de l\u00e2ng\u0103 Anten\u0103.<\/p>\n

De obicei, modulul are priza proprie. A\u0219adar, \u00eel pute\u021bi alimenta de la o surs\u0103 de alimentare separat\u0103 de aproximativ 12V \/ 1A sau 5V \/ 2A.<\/p>\n

Aceasta pentru<\/span> puterea maxim\u0103 sau puterea maxim\u0103 de intrare pentru modul la efectuarea apelurilor.<\/span><\/p>\n

Dar, de asemenea, pute\u021bi alimenta modulul direct de la Arduino<\/span> ca <\/span>pe <\/span>orice alt s<\/span>hield<\/span>. Acest lucru va face ca Vcc \u0219i GND ale modulului s\u0103 fie conectate la Vcc \u0219i GND de la placa Arduino, <\/span>dar acesta alimentat la +5v \u0219i 2A (acest lucru nu prea este recomandat, deoarece acest modul necesit\u0103 o putere mare \u00een modul transmisie).<\/span><\/p>\n

Not\u0103 : C\u00e2nd alimenta\u021bi modulul de la o surs\u0103 de alimentare extern\u0103, Arduino nu poate fi alimentat din modul. Deci, ave\u021bi nevoie \u0219i de o surs\u0103 de alimentare separat\u0103 pentru Arduino.<\/p>\n

Pute\u021bi porni \u0219i opri modulul ap\u0103s\u00e2nd butonul <\/span>POWER<\/span> pentru o secund\u0103.
\nPute\u021bi face acest lucru cu u\u0219urin\u021b\u0103 de fiecare dat\u0103 c\u00e2nd trebuie s\u0103 v\u0103 utiliza\u021bi modulul.<\/span><\/p>\n

Dar dac\u0103 dori\u021bi ca modulul dvs. s\u0103 func\u021bioneze mereu,<\/span> trebuie s\u0103 porni\u021bi automat modulul folosind func\u021bia Software Power ON.<\/span><\/p>\n

Ave\u021bi nevoie doar de trei lucruri pentru a utiliza aceast\u0103 caracteristic\u0103:<\/span><\/p>\n

1- Trebuie uni\u021bi pinii<\/span> JP Jumper <\/span>de <\/span>pe modul. Acest jumper activeaz\u0103 caracteristica din hardware-ul modulului.
\n2- Trebuie s\u0103 conecta\u021bi Arduino PIN 9 la PIN 9 pe modul \u0219i acest PIN va fi dedicat exclusiv acestui scop.
\n3- Trebuie s\u0103 rula\u021bi fragmentul de cod care alimenteaz\u0103 modulul. Acest cod simuleaz\u0103 de obicei ap\u0103sarea butonului Power pentru o secund\u0103.<\/span><\/p>\n

Pute\u021bi comunica \u0219i controla SIM900 GSM Module folosind comenzi AT folosind func\u021bii <\/span>Serial()<\/span><\/strong> sau <\/span>SoftSerial()<\/span><\/em>.
\nExist\u0103 at\u00e2t de multe comenzi utile AT pe care le pute\u021bi utiliza \u00een mod obi\u0219nuit.<\/span><\/p>\n

De exemplu:<\/p>\n

– Answer incoming call : GPRS.println(„ATA;”);<\/span><\/strong><\/p>\n

– Hang up a call : <\/span>GPRS.println(„ATH;”);<\/span><\/strong><\/p>\n

Receiving a Call<\/span><\/strong><\/h4>\n

void ListenToCall()
\n{
\n\/\/ Display any text that the <\/span>shield sends out on the serial monitor
\nif(GPRS.available() >0) {
\n\/\/ Get the character from the cellular serial port
\n\/\/ With an incomming call, a „RING” message is sent out
\nincoming_char=GPRS.read();
\n\/\/ Check if the shield is sending a „RING” message
\nif (incoming_char==’R’) {
\ndelay(10);
\nSerial.print(incoming_char);
\nincoming_char=GPRS.read();
\nif (incoming_char ==’I’) {
\ndelay(10);
\nSerial.print(incoming_char);
\nincoming_char=GPRS.read();
\nif (incoming_char==’N’) {
\ndelay(10);
\nSerial.print(incoming_char);
\nincoming_char=GPRS.read();
\nif (incoming_char==’G’) {
\ndelay(10); <\/span>
\n<\/span>Serial.print(incoming_char);
\n\/\/ If the message received from the shield is RING<\/span><\/p>\n

Called = Called + 1 ;<\/p>\n

delay (1000);<\/p>\n

}
\n}
\n}

Making a Call<\/h4>\n

void Call_PhoneNumber()<\/p>\n

{ GPRS.println(„ATD + xxxxxxxxxx;”);<\/p>\n

delay(1000);<\/p>\n

}<\/p>\n

Alimentarea Arduino<\/span> UNO<\/h4>\n

A\u0219adar, pute\u021bi alimenta modulul GSM de la o surs\u0103 de alimentare de 12 V, dar trebuie s\u0103 v\u0103 alimenta\u021bi placa Arduino sau microcontrollerul principal.
\n\u00cen acest caz, este posibil s\u0103 ave\u021bi nevoie de o alimentare suplimentar\u0103 de 5V.
\nAsta \u00eenseamn\u0103 c\u0103 poate furniza Arduino sau Microcontroller at\u00e2t timp c\u00e2t este conectat la sursa de alimentare.<\/span><\/p>\n
