Introduction For many electronics projects, AVR microcontrollers are commonly used. However, as a beginner, uploading or flashing code to an AVR can be challenging to understand. When other programming hardware is unavailable, an Arduino board can help burn bootloaders onto AVRs. It also enables creating and testing AVR programs. Therefore, this article will demonstrate using

Hitag transponders are employed in a wide range of car keys to prevent theft and unauthorized starting of vehicles. They are also a contributing factor to the increased cost of duplicating car keys for many models that incorporate this technology. Nevertheless, there is currently a software developer who collaborates with these transponder keys, all thanks

In this project, we will establish I2C communication between two Arduino boards. Additionally, we will revisit some fundamentals of Arduino I2C communication, serving as a concise recap of what we’ve previously covered in detail in an earlier Arduino I2C Tutorial. We will explore all three potential scenarios for I2C communication and develop three distinct Arduino

When is 14 volts not actually 14 volts? Given [Anders Nielsen]’s recent struggles with erasing an old-school EEPROM, it’s when you really need it that things tend to go pear-shaped. A little background is perhaps in order. [Anders] is working on a scratch-built programmer for ROMs to complement his 65uino project, which puts a complete 6502 computer into the

In May, Arduino released a guide on how you can create a UPDI programmer for under $10. Now Dlloydev has posted a guide on Github how to make an Arduino Nano HV UPDI programmer. The Nano HV UPDI programmer will enable you to use the additional configuration settings for the UPDI pin without the fear of getting locked out from the MCU. The Nano

Thanks to: http://jeonlab.wordpress.com/ For relatively small (less number of pins than ATmega328) projects, ATtiny series, ATtiny45 or Attiny85 are good choice in terms of its physical size (8-DIP or 8-SOIC) and low power consumption. There are many ways to program it. One of the popular device is USBtinyISP and DASA. Both of them work very well with WinAVR (AVRdude). I’d
