Hello
I am new to hardware and my ques may seem stupid. I apologise for that.
I wanted to step down 6.3V to 5V and I did that using a 1.75 Mohm resistor.
Although when I connect it to the module ( DRM -which requires 5v) the voltage drops to around 0.3V
Is it because the resistor is consuming...
Hi. sorry for the late reply. Was into other project.
As you know I am interfacing my SM5100b gsm module with arduino pro mini.
As you suggested I tried connecting the module with the other system and it
is responding.
I also tried connecting the arduino and hyperterminal together, but the...
I was trying out the solution you had asked me to. I can do it only during my office hours. I figured out that now the hyperterminal itself is not responding then going to the circuit would be secondary, that is why I did not post the circuit.
Com10 is correct but the hyperterminal is not...
hi. I tried connecting the gsm module to the hyperterminal again, this time I am not gettin any response when I type AT or anything else.
I have checked the comport well its COM10.
hey my GSM module is working with the hyper terminal, and it works.. When I connected it to the arduino pro mini and gave the following connections- supply,gnd, rx-rx,tx-tx, it is not working.
my simple code -
char a[30]="AT+CMGR=1";
char b[40];
int i;
int j;
void setup()
{
Serial.begin(115200)...
Hi
This is my code..
I am not able to read the RFID tag. I am not very sure of the address, length,checksum and reset reader as I already said.
#include <Wire.h>
#include <EEPROM.h>
#define MAX_NO_CARDS 3
byte tag[4];
void setup()
{
Wire.begin();
Serial.begin(9600)...
Hello
I had written my first code in arduino using the Wire Library.
Could you kindly tell me where do I find the address of my RFID ( ID2); reset reader ; length and the cheksum as in the code:
eg.
Wire.beginTransmission(0x42); // the RFID reader's address is 42
Wire.send(0x01)...
Hi I have one more doubt as this is the first time I m working with GSM Modules.
The schematic of the MC37i seems very complicated.
As I will be requiring only SMS features of GSM Module, I can just avoid the other connections.
But the charging of the GSM module also looks a little complicated...
Hi
I am interfacing Arduino pro mini with MC37i Gsm module.
Could you kindly tel me where the connections rts,dcd,cts,dtr,dsr of the gsm
will be connected in arduino.
Thank you
