Arduino boards can act as a programmer tool for other AVR microcontrollers using an Arduino ISP and is one of the easiest and cheapest methods for programming AVR MCUs. The Arduino in-system ...

This sketch can be used to let one Arduino program a sketch or bootloader into another one, using the ISP programming pins. This sketch is based on OptiLoader, but modified for use with Adafruit's ...

That's why I want to close a gap with this article about how to program an ATtiny85 with an Arduino via PlatformIO. The first step is to modify the Arduino's behavior, transforming it into a capable ...

Step 1: Configuring Arduino Uno as an ISP: Since ATtiny85 is just a microcontroller, it requires an ISP (In-System Programming) to be programmed. So to program the ATtiny85, we need to first configure ...
