Hi @here,
Today’s Office Hours (https://app.livestorm.co/devheads-community/devheads-weekly-office-hours-1) will see how people are using or plan to use AI/ML in development (to build something, not building AI). So I’d like to get a pulse on whether any of you actually are using it for work or plan to in the future

Hi Devs

, Can I connect two PMS7003 sensors to one Arduino board to collect data from both sensors simultaneously? If so, which Arduino board should I buy? Can you provide any helpful links? Thank you

Well i suggest using the Arduino Mega 2560, as it has multiple serial ports.

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

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.
