For the Bluetooth project, I will advice you to get an Arduino board and Bluetooth module because Proteus may fail. My original Arduino board is #3500 and Bluetooth module is #3000. If you buy the hardware from us, I will send a working Bluetooth - App inventor code to you.

For the training course, you can start with the Arduino project design. Presently I am in Lagos but we do online DIY training.
You will not regret having a course with us

I just sent you a pm. Thanks

  digitalWrite(trigPin, HIGH);
  delayMicroseconds(10);
  digitalWrite(trigPin, LOW);
 
  // Read the signal from the sensor: a HIGH pulse whose
  // duration is the time (in microseconds) from the sending
  // of the ping to the reception of its echo off of an object.
  pinMode(echoPin, INPUT);
  duration = pulseIn(echoPin, HIGH);
 
  // Convert the time into a distance
  cm = (duration/2) / 29.1;     // Divide by 29.1 or multiply by 0.0343
  inches = (duration/2) / 74;   // Divide by 74 or multiply by 0.0135
  
  Serial.print(inches);
  Serial.print("in, ";
  Serial.print(cm);
  Serial.print("cm";
  Serial.println();
  
  delay(250);
}

You can create a gist and share it here so it can be readable.

Esp32 can do better. You get everything on one board.

ESP32 is overkill. It is best for IoT based project not for a simple Bluetooth app communication. This project doesn't need internet access

The onboard Bluetooth comes handy in this case and since it is compatible with almost all BLE devices. The WiFi and Bluetooth can't be used at the same time except that people have started finding ways around it.

Arduino with Bluetooth module is quite bulky with too many wiring, library importation and codes.

I understand what you mean but remember the owner may be a beginner. He may get confused when introducing new advance boards

What solution do you guys have if I need to monitor space intrusion using 3G network?

princejude:
We are rolling out state-of-the-art Embedded system designs Courses...

how much fr all courses and where

Since you are sharing source code, make it readable using gist.

Google gist by github

Are the codes not readable?

jeff35:

delta state

Since you are in Delta, we can do online training: I will send the training materials to you with the training kit and step by step instructions.

princejude:

Are the codes not readable?

Are they readable to you?

ugwum007:


Are they readable to you?

No they are not... but you are the only one complaining.

That is because I am interested in reading it.

Bro
Please I need to get in contact with you.
I can't receive mail from here.
If you reply this quote, I will flash my contact.
Thanks
