Thank you for this comment! You are probably right. I didn't know that Arduino is able to read 3.3v signals so I thought that a logic converter is necessary. Turns out that one-way communication could be possible without it and it would only be essential for two-way communication since that may damage lower voltage board.

@@BasementCreationsChannel the signals from sensors are pretty low aren't they? Yes, you don't want an output from arduino going to a click input if there are any

If your having trouble getting the board to read commands I would try adjusting the threshold in the software settings. Its set at 15 by default but increasing this value will increase the acceptable amount of difference from the recording before it recognizes the command. Also, make sure when you record there is as little background noise as possible. As for your code, the only issue I could see is that what you set up as the output for the command if you set it to HIGH or Pulse the code will be different on the microcontroller side for each one. Either that or wiring. Those are the only two common possibilities.

Hi, this module can only recognize pre-recorded phrases and they need to be spoken slowly and precisely so there is a possibility that it will recognize them in sentences but it most likely will be unreliable.

@@BasementCreationsChannel Thank you for your reply

It should be. I used the Arduino Mega so that I could talk to both SpeakUp and PC but if you just want the communication between the Uno and SpeakUp then it should be possible with just one serial port.

Well thats weird. You just need to download .rar file from Thingiverse and unpack it. I just checked and it works well for me, but if you have some problems I can post it right here. #include Servo myservo; int motor1pin1 = 5; int motor1pin2 = 2; char incomingByte; char incomingByte1; int redPin = A3; int greenPin = A4; int bluePin = A5; int Fan = 31; int Lamp = 33; int RedLED = A1; int GreenLED = A2; int YellowLED = A0; void setup() { analogWrite(redPin, 255); analogWrite(greenPin, 255); analogWrite(bluePin, 255); myservo.attach(9); digitalWrite(Fan,HIGH); digitalWrite(Lamp,HIGH); pinMode(motor1pin1, OUTPUT); pinMode(motor1pin2, OUTPUT); pinMode(Fan,OUTPUT); pinMode(Lamp,OUTPUT); pinMode(redPin, OUTPUT); pinMode(greenPin, OUTPUT); pinMode(bluePin, OUTPUT); pinMode(RedLED,OUTPUT); pinMode(GreenLED,OUTPUT); pinMode(YellowLED,OUTPUT); Serial.begin(115200); Serial2.begin(115200); Serial.println("Ready for commands"); } void loop() { ///// if (Serial2.available() > 1) { // read the incoming byte: incomingByte = Serial2.read(); incomingByte1 = Serial2.read(); Serial.print ("Received data = "); Serial.print(int(incomingByte) ,DEC); Serial.println(int(incomingByte1) ,DEC); //// if (incomingByte == 0){ // Fan On Serial.println ("Command: Number One"); digitalWrite(Fan,LOW); } //// if (incomingByte == 1){ // Fan Off Serial.println ("Command: Number Two"); digitalWrite(Fan,HIGH); } //// if (incomingByte == 2){ // Lamp On Serial.println ("Command: Lamp On"); digitalWrite(Lamp,LOW); } //// if (incomingByte == 3){ // Lamp Off Serial.println ("Command: Lamp Off"); digitalWrite(Lamp,HIGH); } //// if (incomingByte == 6){ // Red On Serial.println ("Command: Red On"); digitalWrite(RedLED,255); } //// if (incomingByte == 7){ // Red Off Serial.println ("Command: Red Off"); digitalWrite(RedLED,0); } //// if (incomingByte == 8){ // Green On Serial.println ("Command: Green On"); digitalWrite(GreenLED,255); } //// if (incomingByte == 9){ // Green Off Serial.println ("Command: Green Off"); digitalWrite(GreenLED,0); } //// if (incomingByte == 10){ Serial.println ("Command: Yellow On"); digitalWrite(YellowLED,255); } //// if (incomingByte == 11){ Serial.println ("Command: Yellow Off"); digitalWrite(YellowLED,0); } //// if (incomingByte == 12){ Serial.println ("Command: Servo 0"); myservo.write(6); } //// if (incomingByte == 13){ Serial.println ("Command: Servo 60"); myservo.write(60); } //// if (incomingByte == 14){ Serial.println ("Command: Servo 90"); myservo.write(90); } //// if (incomingByte == 15){ Serial.println ("Command: Servo 120"); myservo.write(120); } //// if (incomingByte == 16){ Serial.println ("Command: Servo 180"); myservo.write(180); } //// if (incomingByte == 17){ Serial.println ("Command: RGB Blue"); analogWrite(redPin, 255); analogWrite(greenPin, 255); analogWrite(bluePin, 0); } //// if (incomingByte == 18){ Serial.println ("Command: RGB Off"); analogWrite(redPin, 255); analogWrite(greenPin, 255); analogWrite(bluePin, 255); } //// if (incomingByte == 19){ Serial.println ("Command: RGB White"); analogWrite(redPin, 0); analogWrite(greenPin, 0); analogWrite(bluePin, 0); } //// if (incomingByte == 20){ Serial.println ("Command: RGB Green"); analogWrite(redPin, 255); analogWrite(greenPin, 0); analogWrite(bluePin, 255); } //// if (incomingByte == 21){ Serial.println ("Command: RGB Purple"); analogWrite(redPin, 125); analogWrite(greenPin, 255); analogWrite(bluePin, 0); } //// if (incomingByte == 22){ Serial.println ("Command: Open the Window"); digitalWrite(motor1pin1, LOW); digitalWrite(motor1pin2, HIGH); delay(800); digitalWrite(motor1pin1, LOW); digitalWrite(motor1pin2, LOW); ; } //// if (incomingByte == 23){ Serial.println ("Command: Close the Window"); digitalWrite(motor1pin1, HIGH); digitalWrite(motor1pin2, LOW); delay(800); digitalWrite(motor1pin1, LOW); digitalWrite(motor1pin2, LOW); } } }

You are right. While making that video I really didn't want to burn the SpeakUp board and I was a little too cautious. But as long as it's a one way communication Arduino should be able to read 3.3V SpeakUp signals without any problems.

@@BasementCreationsChannel I have it working fine, also use a pull down resistor

Hi The code that you can see in 10.55 is just a shorter version of the code that you can download from Thingiverse or even copy from this comment section.
