How it works ?
Hey Guys, I hope you are enjoying your day. let's without wasting time jump on our project. First of all you have to Bootload your Atmega Chip because newly purchased chip can't be used in Arduino . There are several ways for Bootloading your Atmega chip like you can use a bootloader or you can also use Arduino Ide to burn bootloader in the chip .
After you bootload your Atmega IC you can jump on the next part which is connection . In Figure 3 you can see how all 28 pins in Atmega chip works .For using Atmega chip the required connections
are very less .You can easily program the chip using Arduino Uno and use it wherever you want .In this project I have used a pre programmed chip (programmed using Arduino) but if you want to program your chip without Arduino you can use FT232 which will give you the access to fully program your Atmega chip .
If you are using FT232 make sure that you connect the RX (pin2) of your Atmega chip to TX of the USB to serial board, and connect the TX(pin3) of your Atmega chip to the RX of the USB to serial board.
Pin Configuration(Atmega Chips)-:
Pin1 - Reset
Pin2 - RX
Pin3 - TX
Pin4 - Digital pin 2
Pin5 - Digital pin 3 (PWM)
Pin6 - Digital pin 4
Pin7 - VCC
Pin8 - GND
Pin9 - XTAL1
Pin10 - XTAL2
Pin11 - Digital pin 5
Pin12 - Digital pin 6
Pin13 - Digital pin 7
Pin14 - Digital pin 8
Pin15 - Digital pin 9 (PWM)
Pin16 - Digital pin 10 (PWM)
Pin17 - Digital pin 11 (PWM)
Pin18- Digital pin 12
Pin19- Digital pin 13
Pin20- AVCC
Pin21- AREF
Pin22- GND
Pin23- Analog Input 0
Pin24- Analog Input 1
Pin25- Analog Input 2
Pin26- Analog Input 3
Pin27- Analog Input 4
Pin28- Analog Input 5
This is how you can make your own Arduino board and you can customize it as per your choice as you can see I have used Female header pins to give a similar look of Arduino and a voltage regulator IC to
regulate its voltage to 5 volt dc in order to make the chip work.
