Projektlabor Robotik MINTgrün

Ein simpler Schaltplan für das Modul ist in der Dokumentation unter https://www.parallax.com/sites/default/files/downloads/30016-Emic-2-Text-To-Speech-Documentation-v1.1.pdf zu finden. Sobald alles verkabelt ist könnt ihr dieses Beispielsprogramm testen:

include the SoftwareSerial library so we can use it to talk to the Emic 2 module #include <SoftwareSerial.h> #define rxPin 10 Serial input (connects to Emic 2's SOUT pin) #define txPin 11 Serial output (connects to Emic 2's SIN pin) #define ledPin 13 Most Arduino boards have an on-board LED on this pin set up a new serial port SoftwareSerial emicSerial = SoftwareSerial(rxPin, txPin); void setup() Set up code called once on start-up { define pin modes pinMode(ledPin, OUTPUT); pinMode(rxPin, INPUT); pinMode(txPin, OUTPUT); set the data rate for the SoftwareSerial port emicSerial.begin(9600); digitalWrite(ledPin, LOW); turn LED off /* When the Emic 2 powers on, it takes about 3 seconds for it to successfully initialize. It then sends a „:“ character to indicate it's ready to accept commands. If the Emic 2 is already initialized, a CR will also cause it to send a „:“ */ emicSerial.print('\n'); Send a CR in case the system is already up while (emicSerial.read() != ':'); When the Emic 2 has initialized and is ready, it will send a single ':' character, so wait here until we receive it delay(10); Short delay emicSerial.flush(); Flush the receive buffer } void loop() Main code, to run repeatedly { emicSerial.print('V'); emicSerial.print(„0“); Set volume to 0dB (range -48dB (soft) to 18dB (loud)) emicSerial.print('\n'); digitalWrite(ledPin, HIGH); Turn on LED while Emic is outputting audio while (emicSerial.read() != ':'); Wait here until the Emic 2 responds with a „:“ indicating it's ready to accept the next command digitalWrite(ledPin, LOW); Every robot should inherit the three laws of robotics! 1. Law of robotics emicSerial.print('S'); emicSerial.print(„A robot may not injure a human being or, through inaction, allow a human being to come to harm.“); Send the desired string to convert to speech emicSerial.print('\n'); digitalWrite(ledPin, HIGH); Turn on LED while Emic is outputting audio while (emicSerial.read() != ':'); Wait here until the Emic 2 responds with a „:“ indicating it's ready to accept the next command digitalWrite(ledPin, LOW); 2. Law of robotics emicSerial.print('S'); emicSerial.print(„A robot must obey the orders given it by human beings, except where such orders would conflict with the First Law.“); Send the desired string to convert to speech emicSerial.print('\n'); digitalWrite(ledPin, HIGH); Turn on LED while Emic is outputting audio while (emicSerial.read() != ':'); Wait here until the Emic 2 responds with a „:“ indicating it's ready to accept the next command digitalWrite(ledPin, LOW); 3. Law of robotics emicSerial.print('S'); emicSerial.print(„A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.“); Send the desired string to convert to speech emicSerial.print('\n'); digitalWrite(ledPin, HIGH); Turn on LED while Emic is outputting audio while (emicSerial.read() != ':'); Wait here until the Emic 2 responds with a „:“ indicating it's ready to accept the next command digitalWrite(ledPin, LOW); delay(5000); }
