SD SDHC Card Interfacing with ATmega8 32 FAT32 implementation

SD/SDHC Card Interfacing with ATmega8 /32 (FAT32 implementation)

Here is my project on interfacing of SD Card (microSD). microSD cards are available very cheap nowadays, a great option for having a huge memory in any embedded system project. It is compatible with SPI bus, so the interfacing is easy. SD card adapters are also easily available in market, one can easily make a

Thermometer using DS1621 and Nokia 3310 LCD interfaced with ATmega8

I am presenting one application with the Nokia 3310 LCD: Designing a thermometer using DS1621 temperature sensor IC. DS1621 is 8-pin sensor from Maxim, with temp range of -55 to +125 degree C, which can be interfaced with microcontroller over two-wire serial i2c bus. It has operating voltage range from 2.7 to 5.5v. I’m operating

Simple PWM DC motor control using MOSFET H-Bridge with AVR ATmega8

Here is a very simple project of controlling a small DC-motor (taken from an old personal cassette player) with ATmega8. The ATmega8 is having three PWM channels, out of which two are used here. PWM waveforms are fed to MOSFET (RFD3055) H-bridge. Here, direction is controlled using a two-position toggle switch and speed of the

NOKIA 3310 LCD interfacing with ATmega8

Using graphic LCD in a project gives it really a good look and flexibility of displaying different characters and shapes. But, the graphic LCDs are quite costly. The NOKIA 3310 LCD provides a really low-cost solution to add a small graphic display into your project and also good for learning purpose. The LCD is SPI

AVR based monochrome signal generation for a PAL TV using atmega16 micrcontroller

AVR based monochrome signal generation for a PAL TV using atmega16 micrcontroller

Introduction: I have learned some thing about TV in one of my B.tech semester but I forgot most of them. Now I refreshed a few basics and tried to implement a monochrome PAL TV signal generator using an AVR micrcontroller. I was using PIC earlier but later I jumped to AVR because I loves the
