Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...

Some of the latest Microchip AVRs require a UPDI programmer. This guide will show you how to build your own Arduino based programmer using jtag2updi. The new Microchip AVR MCU generation using UPDI ...

Situation: You want to include a timer interrupt service routine in an assembly language program for an AVR-based Arduino. The program will be written, assembled and uploaded using the Arduino IDE.

Turning an Arduino of virtually any sort into a simple AVR 6-pin ISP programmer is old hat. But when Atmel came out with a series of really tiny AVR chips, the ATtiny10 and friends with only six pins ...

The Arduino software comes with an ArduinoISP sketch which allows an Arduino, correctly connected, to flash another AVR chip. With the use of other libraries like Attiny-core, this means you can use ...

Arduino Nano with ATmega328P is available in two variants: "ATmega328P" and the older "ATmega328P (Old Bootloader)". The newer variant uses an optimized bootloader which has double upload transfer ...

The circuit was based on the use of Arduino AVR to build a high voltage programmer which can be used to fix pesky fuses. The circuit was based on the use of Arduino AVR to build a high voltage ...
