Self Made Arduino Board :

Want to save money by making your own arduino clone boards? Or want to make a custom board specifically for your needs, then this project is useful for you. Make arduino board from cheap electronic components available at your local store. Just follow these simple steps.
What are the stuff required to do this project?

Hardware :
1) ATmega328 , ATmega168 , ATmega 8 IC
2) LM7805 IC.
3)16 Mhz crystal.
4)Tactile button.
5)Led’s.
6)Capacitors – 22pF (2 Nos), 10uF (2 Nos), 0.1uF (2 Nos).
7)Resistors – 220Ohm (2 Nos), 1k (2 Nos).
8)Pin headers (Male).28 pin IC socket.
Software :
1) Arduino IDE
Tools :
1)Soldering iron.
2)Solder lead.
3)Prototyping solder dot board / breadboard or materials to etch your own board.

STEP 1 :

Placement Of Components in PCB/BreadBoard:



According to the circuit connect all the components on the Breadboard.
You can either etch a PCB to make your custom board or use a prototyping dot board to merely solder the components on it. Or even arrange them on a breadboard. Connect the components with each other just like in the diagram below. There are only a very few components required to make your custom arduino board. A voltage regulator to supply 5V to arduino. it’s supporting circuitry to filter the voltage; then a 16Mhz cystal along with it’s parallely connected 22pF capacitors that acts as the clock to the arduino. And an led connected to pin no 19 of the ATmega , for testing purposes. Use the schematic if you want to etch your own pcb. Modify the schematic to make arduino board suited for your project.

STEP 2: 

Uploading the code and using the board

Steps :
1) Use Ardunio Uno for uploading/burning the code into the Atmega 328p .
2)Connect with pc and by using the aurdino IDE upload the code.
3)Remove the IC from the Board and fix it on PCB.
or
You can also burn the program using Bootloader.






















Thank You

HOW TO USE USE ULTRASONIC SENSORS IN PROTEUS ?

Image
Hello friends, hope you all are fine. In today’s post, I am going to share an Ultrasonic Sensor Library for Proteus.Using this library you can perform any kind of function with an ultrasonic sensor.                                                                           First of all, let's have a short introduction of an ultrasonic sensor. In the ultrasonic sensor, there are two nodes in which one is transmitter while the other is a receiver. The transmitter sends an ultrasonic wave and this wave strikes to any hindrance present in front of it and then bounces back. This bounced ultrasonic sensor is then captured by the receiver and on the basis of the time taken by this wave to return, the sensor calculates the distance of that obstacle from that sensor. The ultrasonic sensor is usually used for detecting the obstacle in a path and also to find the distance between a sensor and the obstacle. Ultrasonic sensor normally used is HC-SR04, which is also used here in this library.

Hello friends, hope you all are fine. In today’s post, I am going to share Arduino Library for Proteus.  I have already posted few other Arduino Libraries on my blog but those were third party Libraries.This is also third party library.Follow the steps then y You can easily use Arduino boards in Proteus and can simulate any kind of project in Proteus. If you got any trouble then you can ask in comments or can use our Ask Question forum to post your questions. This Arduino Library for Proteus contains following boards in it: • Arduino UNO • Arduino Mega 2560 • Arduino Mega 1280 • Arduino Nano • Arduino Mini • Arduino Pro Mini Let’s get started with Arduino Library for Proteus. • First of all, download this Arduino Library for Proteus.The link is given below of this Post.  • When you download it, you will get a zip file. so, unzip this file and you will get two files in it. • These two files are named as ArduinoTEP.LIB and ArduinoTEP.IDX. • Copy

HOW TO GET HEX FILE FROM ARDUINO ???

HOW TO GET HEX FILE FROM ARDUINO ??? Hello friends, hope you all are fine.Firstly I am wishing you a Happy New Year. In today’s post, I am going to share How to get Hex File from Arduino.If you have worked on PIC Microcontrollers or Atmel etc then you have seen that you always get hex file from their compilers and then you burn that hex file in the respective microcontroller using their programmer or burner. But that’s not the case with Arduino. In Arduino boards, you simply plug it into your computer and you hit Upload button and the code automatically gets upload in Arduino boards. It doesn’t create any hex file.There are many cases when hex file is required. For example, instead of using Arduino board you just want to use the ATmega microcontroller then the easiest way is to write the code in Arduino and then get its hex file and upload it in your microcontroller, which makes the task quite easy. Another example is Proteus simulation, when you want to simulate your Arduino boar
