It is a 14 pin DIP package so it’s breadboard friendly.
Of course, you don’t need to buy or make a programmer if you have a Raspberry Pi, because it can do the job.įor this tutorial, I’ll be using an ATtiny24 AVR chip. I also have a DIY USB programmer that I developed. Adafruit sells a USB programmer kit that works well. The code is usually written on a PC and then compiled and uploaded to the AVR with a programmer. AVR chips run code that can be compiled from basic, C and assembly language. Often a single AVR can replace a complicated electrical circuit with multiple components. Offloading the operations to an AVR can reduce the load and is often cheaper than a dedicated LCD driver IC. Also some devices such as multi-digit LED displays can consume too much of the Pi’s CPU resources. Futhermore, there are times when there is no Pi driver available for a component such as a graphic display, but an AVR driver is available.
They are a great solution for controlling projects because they are small, inexpensive, fast, can run off batteries and can interface with just about any DIY electronics including the Pi. They can often be purchased on eBay for a couple of dollars. AVR chips such as the Atmel ATtiny or ATmega are powerful 8 bit microcontrollers. My projects section contains many AVR based projects.
