In this tutorial, we will learn how to interface a switch(push button) with ATMEGA16 using AVR studio. In the previous video, we learnt how to interface LEDs with ATMEGA16 using AVR studio. The push-button is a component that connects two points in a circuit when you press it. The example turns on an LED when you press the button. Here we have connected two push button to PORT C in  PC0 & PC1. And for LEDs connection please refer my previous blog. Components Required:- AVR Controller(Atmega16) LEDs Push Button Connecting Wires USBASP Programmer Dump the following code after connection  and select chip ATMEGA 16. #include<avr/io.h> #include<util/delay.h> void main()  {    DDRB=0b11111111;    int S1;    int S2;      while(1)    {     S1=PINC&0b00000001;     S2=PINC&0b00000010;     if(S1==0b00000001)     {      PORTB=0b00000001;      _delay_ms(100);      }      if(S2==0b00000010)     {      PORTB=0b00000010;      _delay_ms(100);  

In this tutorial, we will learn, how to interface an LCD (liquid crystal display) with ARDUINO.  An LCD screen is an electronic display module having a flat panel display or we can say it’s an electronically modulated optical device that uses the light modulating properties of liquid crystals. We will interface a 16x2(16 columns and 2 rows) LCD. Other variations are also available like 8x1,10x2 etc. It is having a wide range of applications; they are also preferred over the 7-segment display as they are cheap, easily programmable and also have the leverage to display special characters. Now let us interface Components Required 16x2 LCD                   1No. Resistor 560ohms        1No. Potentiometer 10k      1No. Arduino UNO               1No. Few connecting wires Breadboard Follow the image below for circuit connection reference. After making the circuit dump the code given below. #include<LiquidCrystal.h> LiquidCry

In this tutorial, we will learn how to interface LED with Atmega16 using AVR Studio . An embedded system is built around a processor. The design goals of an embedded system are to reduce size, cost and power consumption and to increase performance and reliability. The microprocessor we are using is ATMEGA16 . The processor has limited internal memory, and if this is not sufficient for a given application external memory devices are used. The hardware also includes any components that facilitate the user-application interaction such as display units, keypad. The light-emitting diodes are used for getting status information, such as power on, check output(high/low). You all must have observed led decoration lights, which can glow in different patterns. First, we will learn to interface a single Led and then 8 LEDs to learn a simple toggling technique. Components Required:- AVR controller(Atmega16) LEDs Connecting wires USBASP Programmer For

In this tutorial, we will learn how to interface a 7 SEGMENT DISPLAY with Arduino. A 7 SEGMENT DISPLAY consists of 8 LEDs and 10 pins,2 common pins are shorted and supplied with 5 volts from Arduino through a resistor and other 8 pins are connected to digital and analog pins. 7 Segment Display can act as a substitute for LCDs if we want to display numbers. Shown below is the internal architecture of a 7 segment display. Now let’s interface the 7 SEGMENT DISPLAY. Components required Arduino Uno                       1No. 7 Segment Display              1No. Resistors                             1No.            100 ohms             Connecting Wires Breadboard There are two types of LED 7-segment display The common cathode (CC)  Common anode (CA) In CC type the cathode of all the LEDs is connected together and similarly in CA type. In CC type we have to ground the common cathode pin and power up segments to illuminate it, the reverse happens

In this tutorial, we will learn how to interface a servo motor using Arduino UNO. The motor inside the setup of a servo is attached by gears to the control wheel. When the motor rotates, the potentiometer’s resistance changes hence the control circuit can precisely regulate how much movement there is and in which direction. The motor’s speed is proportional to the difference between its actual position and desired position. When the shaft is near the desired position it turns slowly else fast. This is called proportional control. They are controlled by sending PWM (pulse width modulated) signals through the control wire. They are available in many sizes and are of three types Positional rotation  Continuous rotation  Linear The most common type is the positional rotational one. So now we are familiar with the motor let us interface it Components Required: Servo motor 1No Arduino UNO 1No Few connecting wires Breadboard Follow the video below for cir

Since now we all have worked a lot with led,s let us show you one of the projects made by us with the help of bulk of led,s. A led matrix cube Below is the video of our project. Working description: The above is made by combining led,s in a regular fashion in cubical shape. All types of patterns can be generated in the cube and also various shapes like square, triangle etc. Whatever pattern comes to your mind you can generate that by altering the code.
