VARIABLES EXAMPLE IN C LANGUAGE

Simple example to explain how variables are used.
Syntax:
int num;
float decimal;
char alphabet;
double number;
Here int, float, char and double are datatypes(type of data).
Here num,decimal,alphabet, number are variables. They may have any name.
Example describes getting two values from user and their addition .
#include<stdio.h>
int main()
{
int num1,num2;// Global declaration
printf("Enter the first number");
scanf("%d",&num1);
printf("Enter second number");
scanf("%d",&num2);
add(num1,num2);//Passing value to a  function "add()"
return 0;
}
void  add(int x,int y)
{
int total; // local variable
total = x + y; // performing actual addition
printf("The addition of two number is: %d",total); //Displaying addition of two numbers on screen
}
Output:
The addition of two number is: 5
Description:
Here we have used two types of variables.
1.Local variable (ex : total,x,y...)
2.Global variable (Ex: num1,num2)
We make those variable as global variable which we need to use throughout the code.
We make those variables as local variable which we would require very few times.

Interfacing Load Cell with Raspberry Pi 3 (via HX711) ⚖️

Interfacing Load Cell with Raspberry Pi 3 (via HX711) ⚖️ Interfacing Load Cell with Raspberry Pi 3 (via HX711) ⚖️ A load cell is a transducer that converts force (weight) into an electrical signal. The HX711 is a precision 24-bit analog-to-digital converter (ADC) designed for weigh scales. Today we’ll connect a load cell to Raspberry Pi 3 using the HX711 module. ๐Ÿงช ๐Ÿ”ง Components Required Component Quantity Raspberry Pi 3 1 Load Cell 1 HX711 Module 1 Jumper Wires 6 Breadboard (optional) 1 ๐Ÿ”Œ Pin Connections HX711 Pin Raspberry Pi Pin Pin Number VCC 5V Pin 2 GND Ground Pin 6 DT GPIO 5 Pin 29 SCK GPIO 6 Pin 31 Figure: Load Cell connected to Raspberry Pi 3 via HX711 ๐Ÿ’ป Python Code from hx711 import HX711 import RPi.GPIO as GPIO import time hx = HX711(dout_pin=5, pd_sck_pin=6) hx.set_reading_format("MSB", "MSB") hx.set_reference_unit(1) hx.reset()...

Interfacing Sound Sensor with Raspberry Pi 3

๐Ÿ”น Overview The KY-037 is a high-sensitivity sound detection sensor that can detect noise levels in the environment. It provides both analog and digital outputs. In this tutorial, we’ll interface the digital output of KY-037 with Raspberry Pi 3 Model B+ (without using an ADC like MCP3008) and detect sound events.
