“In this project, we’ll build circuits for programming two different Atmel microcontrollers and we’ll discuss the necessary software setup. This project will describe the construction of two very similar circuits: one for programming an ATmega328P and another for programming an ATtiny45. The article will provide a complete schematic diagram of the programming circuits as well as detailed photographs of the solderless breadboard assemblies. In addition, Atmel Studio 7 IDE (Integrated Development Environment) will also be introduced.”
