At home I have a salt lamp. This lamp needs a regular small 15 Watt light bulb that lights up and warms up the lamp. When the lamp is switched on you normally should not dim the lamp because of the lamp heat that the salt lamp needs to get rid of the moisture it […]

The instructable created by me will help you to build a huge memory capactiy which will come in handy for many projects and measurements. The memory card is suitable for multi-usage and can be way more realaiable in comparison to flash cards and other type of soft memory. The life span of those CMOS EPROM’s

This library implements an SD card Data Logger that runs on ATmega. It has a small footprint, so it can be loaded on an ATmega8, leaving space for user code. It supports SD and microSD cards formatted with FAT16. It also features log rotation.The “Petit FAT File System Module” by ChaN (http://elm-chan.org/fsw/ff/00index_p.html) it is used to write

This project explains how to interface the SD card with an AVR microcontroller. In this project an ATMEGA16 microcontroller is used. The microcontroller runs on 5V power supply with a built in crystal frequency of 8 MHz. A 2GB SDSC card from Transcend is used in this particular project, but the code will work with most of the SD

In any microcontroller the Boot-Loader is the first code which executes before the application code does. The major function of the Boot-Loader is to load the application code into the flash memory of the microcontroller and execute it. In AVR microcontroller the Self Programming Mode (SPM) helps the Boot-Loader to load a particular application from

You might have noticed the Slaveflash I built with an Attiny 24, the instructable can be found here: Slaveflash-trigger-for-digital-with-Attiny24 After building the first prototype I collected all my old flashes I got over the years and had four more slaveflash-triggers to built. I already figured out an PCB-Layout for the SOIC-version of the attiny 24.

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
