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.

Automatic Water Pumping System

Image
Here's a "Automatic Water pumping system" which controls the  water pump motor. The motor gets automatically switched on when water in tank falls below the lower limit . Similarly, its get switched off when the water is filled up( upper level ). This circuit is built with the help of 555 Timer IC Which is best and cheap.    Material required-: PCB Board 555 Timer IC 1k ohm Resistor x 2 220 ohm Resistor x 2 2 Pin Screw Terminal 5V Relay Battery(9v) Transistor (BC 547) Diode (IN4007) Led  Automatic Water pump Circuit-: If you guys have seen my previous post of relay module you must somewhat familiar with upper part of the circuit ,in which we just have to trigger the base pin of transistor to turn the relay on .Just like that, Here we are using output pin (3) of 555 IC to trig the base pin .   When the water level goes up and touch the pin 6 of 555 IC ,output of Pin 3 goes low(0) which switches off the motor. When the level goes below the low level ,that is pin 2 ...

Wireless Communication Between Two Arduino Board Using HC-05 Module

Image
In this post I will show you how you can communicate between two Arduino Boards using HC-05 Module. I am using Arduino IDE's version 1.8.7.  There are now newer modules that use a 3.0-20170601 firmware due to which module gives an error, But I will show you how you can fix this error. Just follow the exact same steps listed below and you will not get any error. Material Required-: PCB Board Arduino Uno x 2 Led Bluetooth Module(HC-05) x 2 Push Button (Switch) Resistor (1k ohm) Jumper Wire Connection for AT Mode -: 5V to Arduino 5V GND to Arduino GND TX to Arduino TX(D1) RX to Arduino RX(D0) Enable Pin to 5V Connections for AT Command Mode Step-1: Upload Blank code on Arduino Board. Step-2: While connecting supply to module long press the "Key Button" situated above enable pin. Now, You will see a delay in flashing of HC-05 led, that's means you are successfully entered in AT Command Mode. Step-3: Now open serial monitor . Remember that HC-05 requires Both "NL and ...
