Automatic night lamp project in Proteus with Arduino Library

Automatic night lamp is such type of lamp,which glow only on night time automatically and remain off during day time.
 Today we are going to make automatic night lamp in Proteus with Arduino Library for this ,we  need Proteus simulation software & Arduino programming software.

You have to follow the following steps to make the automatic night lamp project.



step. 1. Write a program in Arduino programming software.
     
code:-
int led =13;
int ldr = A0;
void setup()
{ pinMode(led,OUTPUT);
   pinMode(ldr,INPUT);
   Serial.begin(9600);
} // to establish the serial communation between arduino and computer.
void loop () {
 int value = analogRead (ldr); // to read the analog value of the sensor
   Serial.println(value);   // to print the serial value in  serial monitor
  if (value>500)
 digitalWrite(led,HIGH);
else
 digitalWrite(led,LOW);

}

then go to file -> preference & tick mark on compilation.
step ii
  Verify the program by click on ta tick botton on arduino software as shown in figure
copy the hex file after verifying the program 
link here is inside the red color rectangular box and have an extension .hex

step iii
 Open the Proteus  and add the necessary component
   here for automatic night lamp we need following component
   i. Arduino
  ii.LDR
 iii. LED
iv. Resistor
 we can pick this component from Proteus library by pressing "p" on keyboard.A dialog box will appear then we write the necessary component then we take those component.for details figure are shown below.

take  all the necessary components and arrange the ckt as shown in figure below

double click on the arduino kit and paste the link copied before
Now  when the ckt is played then during the day time the value of sensor is low during the day time and high during the night time.

During day time
During the night time 
during the night time the led is glow because the led is only glow when LDR value is greater than 500,

Multiple mcp23017 interfacing with Arduino

MCP23017 is the I/O port extender that runs on 12C. It is 16-bit I/O expender.in this tutorial we are going to interface the single and multiple  mcp23017 with arduino.  fig:- mcp32017 module IT has 16 I/O ports from PA0 to PA7 and PB0 to PB7. first of all we are going to interface the single mcp23017 with Arduino. For this  connect the circuit as shown on figure. Download the library for mcp23017  from  sketch-- include library -- manage libraries.
