Introduction USART is one of the primitive inter-device communication protocols. It is not used in modern computers. But still, a few mother boards come with the module necessary for an USART communication. Here, in the case of PCs, the port is known as COM port and it follows RS232 protocol. It is no different from […]

In this article, we will explain how to communicate to an external EEPROM from the AVR Atmega32 MCU using the I2C communication protocol. So let’s begin our tutorial on how to interface an EEPROM (AT24C16A) with AVR Atmega32.You will usually need an external EEPROM when your system has a certain set of user configurable settings

Introduction Our project is to make a color video game that runs primarily on the ATmega 1284P. To do this, we adhered to the NTSC standard for color video. The sync signals used for NTSC are generated on the ATmega 1284P itself, and all game logic is implemented on the microcontroller as well. To actually

Pulse Width Modulation (PWM) is a technique widely used in modern switching circuit to control the amount of power given to the electrical device. This method simply switches ON and OFF the power supplied to the electrical device rapidly. The average amount of energy received by the electrical device is corresponding to the ON and

Temperature monitoring have wide application in daily life. In modern day keeping an eye on temperature of places such as server rooms, hospital rooms, warehouses and green houses can help solve many problems. But with the use of normal temperature sensors, someone needs to go to the place in order to view the temperature. But

Servo motors are so called “closed feedback” systems. This means that motor comes with control circuit, which senses if motor mechanism is in desired location and if not it continuously corrects an error until motor reaches proper point. Servo motors are widely used in robotics, remote controlled planes, vehicles. So they come in many shapes

Sometimes in embedded design you may want to go wireless. Might be you will want to log various readings of remotely placed sensors, or simply build a remote control for robot or car alarm system. Radio communications between two AVR microcontrollers can be easy when specialized modules are used. Lets try to run very well
