Hey everyone! as a person who love to create 3D project i recently discovered that Blender can be used for electronic too , design and visualization, such as PCBs and simulating assembly processes. and even creating interactive 3D renderings for better presentations for it . Has anyone here tried using Blender for electronics, or do you have any tips on getting started with this?

aymen ammari•6/10/24, 4:52 AM

I'm new to arduino coding and we are tasked with making a smoke sensor that sends a sms message to a user when it detects smoke. One problem that we've encountered is that our gsm module 900a can't seem to find a network (the status LED blinks every second rather than every 3 seconds). How can we fix this problem?

I will provide the code below

int buzzer = 8;
int smokeA0 = A5;
int sensorThres = 0;

#include<SoftwareSerial.h>

SoftwareSerial GSM (9, 10);

void setup()
{
pinMode(buzzer, OUTPUT);
pinMode(smokeA0, INPUT);
Serial.begin(9600);
GSM.begin (9600);
delay(100);
}

void loop() {
int analogSensor = analogRead(smokeA0);

if (analogSensor > sensorThres)
{
digitalWrite(buzzer, HIGH);
delay (1000);
Serial.println("AT+CMGF=1");
delay(1000);
Serial.println("AT+CMGS="+639053188487"\r");
Serial.println("smoke detected alert");
Serial.println((char)26);
delay(100);

}
else
{
digitalWrite(buzzer,LOW);
}
delay(50);
}

I have not tried this before , but it will be helpful to check out the Quectel EC200 series AT commands documentation for detailed explanations of the +QMTCONN and +QMTSTAT responses, particularly error codes like "3" so you can find specific troubleshooting steps for this particular error code

Try using the serial monitor to see if you are actually getting value from the module, also check your pin configuration

Ben•6/11/24, 5:55 AM

Test the sim module,

#include <SoftwareSerial.h>

//Create software serial object to communicate with SIM900
SoftwareSerial mySerial(7, 8); //SIM900 Tx & Rx is connected to Arduino #7 & #8

void setup()
{
//Begin serial communication with Arduino and Arduino IDE (Serial Monitor)
Serial.begin(9600);

//Begin serial communication with Arduino and SIM900
mySerial.begin(9600);

Serial.println("Initializing...");
delay(1000);

mySerial.println("AT"); //Handshaking with SIM900
updateSerial();
mySerial.println("AT+CSQ"); //Signal quality test, value range is 0-31 , 31 is the best
updateSerial();
mySerial.println("AT+CCID"); //Read SIM information to confirm whether the SIM is plugged
updateSerial();
mySerial.println("AT+CREG?"); //Check whether it has registered in the network
updateSerial();
}

void loop()
{
updateSerial();
}

void updateSerial()
{
delay(500);
while (Serial.available())
{
mySerial.write(Serial.read());//Forward what Serial received to Software Serial Port
}
while(mySerial.available())
{
Serial.write(mySerial.read());//Forward what Software Serial received to Serial Port
}
}
Once you have uploaded the sketch, open the serial monitor at baud rate 9600. You should see the output below on the serial monitor.
