IoT Based Fingerprint Attendance System Using Evive (Arduino Based Embedded Platform)

Leave a Comment / Using Arduino / By

Now, you can easily track attendance and clock working hours with the help of this easy and fun to make DIY fingerprint scanner! We’ll be using ThingSpeak to store and retrieve the data. All you require is a cardboard piece, some colored paper, a fingerprint sensor, evive, and lots of DIYing! Ready for some scanning …

Under $8 Arduino Serial Data Logger – Record to SD Card

Leave a Comment / Using Arduino / By

Disclosure: This project operates the ATmega328-P-PU outside the published ATmel specifications: According to ATmel, the 328P requires slightly over 3.3V to reliably start the oscillator at 16MHz and to otherwise perform acceptably.  Lab testing here at SofKinetics has shown that the ‘board-duino’ 328P-PU can withstand below freezing and above 130F temperatures and that the 16MHz crystal …

microSD FAT32 testing using Visual C++ Using Atmega

Leave a Comment / Using Atmega / By

This post presents a way for testing and learning the FAT32 system on microSD/ SDHC cards without building the hardware with microcontroller, thanks to Henry Yiu. This project uses the FAT32 library available in my previous post, but does away with the microcontroller part. So, you can use this code with a PC and USB card reader and get insight …

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

Leave a Comment / Using Atmega / By

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 bread-board adapter by soldering …

Slaveflash

Slaveflash with Attiny24 ver. 2.0

Leave a Comment / Using Atmega / By

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. But the biggest …

SPM To load Application

How To Use SPM To load Application from EEPROM Using Atmga

Leave a Comment / Using Atmega / By

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 where the application binary is stored.The …
