  • Arduino Password Security System With Magnetic Door Sensors

    Hi,please team I need your help in detecting why my code is not sending the value of voltage in the sms alert received. Please kindly find below my code, once the threshold is reached, the gsm sends an sms to my line but it does not contain the value of the battery voltage; it only displays 0.0V. please help me fix this:..............................................................#include <SoftwareSerial.h>#define LIMIT 23.0 // Change it to your favoured value in Celsius.#define NUM_SAMPLES 10SoftwareSerial GSMSerial(9, 10);//Connect 9 to TX of GSM and 10 to RX of GSMint sum = 0;unsigned char sample_count = 0;float voltage = 0.0;void setup() { // Setting up the Arduino. GSMSerial.begin(19200); // Setting the baud rate of GSM Module Serial.begin(19200); // Setting the ba...

    Please I am a novice on Arduino still practicing. I want help to write a code to monitor a battery bank of 24V (A0 probably), an AC 230V (A1 probably), an auxillary ac volt 230V AC (A2 probably), temperature and humidity probably A3/A4. Also would want them accesible on the web remotely and possible in graphical and block form.Please how do i start or how can i achieve this please.
