Problem after uploading code in arduino
September 29, 2019 - 4:26pm

Hello,

I have been trying to make a fingerprint voting system using arduino but after successful setup of the hardware and program compiled when it is being uploaded to the arduino uno board it says "module not found check connection".The code I have used is-

 

#include<EEPROM.h>
#include<LiquidCrystal.h>
LiquidCrystal lcd(13,12,11,10,9,8);
 
#include <Adafruit_Fingerprint.h>
uint8_t id;
Adafruit_Fingerprint finger = Adafruit_Fingerprint(&Serial);
 
#define enroll 14
#define del 15
#define up 16
#define down 17
#define match 18
#define indVote 6
 
#define sw1 5
#define sw2 4
#define sw3 3
#define resultsw 2
#define indFinger 7
#define buzzer 19
#define records 25
int vote1,vote2,vote3;
 
int flag;
 
void setup() 
{
    delay(1000);

    pinMode(sw2, INPUT_PULLUP);
    pinMode(sw3, INPUT_PULLUP);
    pinMode(resultsw, INPUT_PULLUP);
    pinMode(buzzer, OUTPUT);
    pinMode(indVote, OUTPUT);
    pinMode(indFinger, OUTPUT);

Check in device manager
September 30, 2019 - 8:46pm

This probelm is no where related to the program. Your computer is not discovering your Arduino Board. Open device manager and check if your arduino is being discovered. 

The problem could be because of a missing driver or a faulty programming cable

Thank you sir for the reply, sir can you please assist me with the circuit installing as I think there must be some connection error which I am doing.It will help me a lot.

Thank You.

Drivers Update Required for the Board
May 9, 2020 - 1:09pm

There is an issue with the drivers for the board you are using. For that go to device manager in your OS, click on the port option, if your board is discovered by the system then there must be a port shown there like COM3 etc. Otherwise, your board is in other devices tab, when you plugged the arduino board with your computer. There is a display "USB-to-Serial232" or other in other devices tab, just right click on it and try to update drivers automatically. After drivers installation done, then you can see the port No. mentioned in the port option. Check that port No. for your board and select that one in Arduino IDE, compile, then upload your code and enjoy the tinkering with your newly added board. Here I would like to suggest you to visit the SSLA for getting better assistance from technical support team of this platform.
