process of simulate Arduino with Proteus.

Simulation is a very powerful tool to understand how the device will work after implementing in real.Before start any project, it is a good practice to simulate it and virtually verify that works. Proteus is a simulation base software.By using this software Arduino can be simulate.Today we are going to simulate arduino in Proteus. We will test arduino Blink program with Proteus.Lets do it...

Before start simulation need to make sure that in File>>Preferences, compilation is marked. Because "compilation" compile the code and generate .hex file.This .hex file is needed for running the Proteus simulation.

Proteus is the software where we run our simulation.First make sure that you have Proteus installed in your operating system.If not, then download and install Proteus.After run the Proteus software, If you don't find arduino in the library.Then, there is a .rar file download it and copy/cut the file.After that paste it into the Proteus library.I am using windows 7 operating system.In my case the location of the Proteus library is, C drive>Program Files>Labcenter Electronics>Proteus 8 Professional>LIBRARY.After that you will find arduino in your library.

Run Arduino IDE and go to File>Examples>01.Basics>Blink and open it.Click on "Verify" button.Then copy(Ctrl+C) the .hex file.

Run the Proteus and draw the circuit like the picture.You can directly connect Led with pin 13.But it is a good practice to add a 220 ohm resistor with led in series.Resistor limits the current flow.Double click on arduino and paste the .hex file in "Program File:".Run the simulation by clicking "Run the simulation" button. LED is Blinking if everything is okay. Congratulation!!!!

This video will show you the process of simulate Arduino with Proteus..

How to make 555 timer circuit & 555 timer led flasher?

In an astable circuit, the output voltage alternates between VCC and 0 volts on a continuous basis.

555 Timer Calculator Overview

The 555 timer shown above is configured as an astable circuit. This means that the output voltage is a periodic pulse that alternates between the VCC value and 0 volts.

How to Calculate Output Voltage Frequency

The frequency is the number of pulses per second. The formula to calculate the frequency of the output voltage is:

f=1.44(R1+2R2)C

$$$$The period is the time covered for one pulse. This is just the reciprocal of the frequency:$$\mathrm{<br>}$$$$f=\frac{1.44}{(R_1+2R_2)C}$$$$\frac{\mathrm{<br>}}{}$$

The period is the time covered for one pulse. This is just the reciprocal of the frequency:

                                         T=1f=0.694(R1+2R2)C

$$\frac{\mathrm{<br>}}{}$$ $$\frac{\mathrm{<br>}}{}$$ The high time (T1) and low time (T0) can be calculated using the formulas below. Note that the period is the sum of the high time and the low time.

T1=0.694(R1+R2)C
T0=0.694R2C

The mark space ratio is the ratio between the high time and the low time or:

                                         Mark Space Ratio=T1/T0

The duty cycle is more commonly used than the mark space ratio. 

The formula for the duty cycle is:

                                   Duty Cycle=T1/T x 100

$$\frac{}{}$$

A 50% duty cycle means the high time is equal to the low time.

If an LED is placed at the output of this astable circuit, 

it will turn on at the same span of time as it is turned off. 

Note that getting an exact 50% duty cycle is impossible with this circuit.

Notes :

Increase C to increase the period (reduce the frequency).

Increase R1 to increase High Time (T1), without affecting the Low Time (T0).

Increase R2 to increase High Time (T1), increase Low Time (T0) and decrease the duty cycle.

Applications Synchronous Circuit Timer:

A synchronous circuit is a digital circuit in which the changes in the state of memory elements, 

commonly flip-flops, are synchronized by a clock signal. Because of their availability and ease of use, 

the 555 astable circuit is the common source of clock signal in many synchronous circuits.

A shift register--an example of a synchronous circuit--is shown below. 

Normally you would connect the output of the 555 astable circuit to the clock pin of this shift register. 

LED Flasher

Although you can build a simpler LED flasher using a single transistor, some resistors, and a capacitor, most people would rather use a 555 astable circuit. See circuit below:

How fast would the LED blink? Of course, you can use our calculator to find that out.  

Tone Generator

The circuit above produces an audible tone and is just one of the many sound-generating circuits that employ the 555 astable circuits. A 150kΩ potentiometer is used to adjust the frequency of the tone. It is possible to preset the output's upper and lower limits to predefined values by adding resistors or trimmers in series with the potentiometer.
