ATtiny microcontroller development for Arduino programmers

ATtinys 是低成本的微控制器，以其小巧的外形和低功耗（在 DeepSleep 期间约为 4-8µA）而令人印象深刻。可以在熟悉的 Arduino 环境（IDE 和 C++）中轻松快速地对 ATtinys 进行编程，因此您可以获得 Arduinos 和 ESP 的廉价替代品。ATtinys 可以使用纽扣电池 CR2032 操作，并且有足够的内存用于常见的 DIY 项目。

整个课程使用 ATtinys 25/24、44/45 和 84 以及 Digispark ATtiny85。

Description
ATtinys are low-cost microcontrollers that impress with their small form factor and low power consumption (~4-8µA during DeepSleep). The ATtinys can be programmed easily and quickly in the familiar Arduino environment (IDE and C++), so you have a cheap alternative to the Arduinos and ESPs. The ATtinys can be operated with a button battery CR2032 and have enough memory for common DIY projects.

For the whole course the ATtinys 25/24, 44/45 and 84 as well as the Digispark ATtiny85 are used.

What we go through in the course

Basics of Atmel ATtiny microcontrollers.

Getting to know different components like transistors, OLED displays, shift registers and much more.

Getting to know different upload variants for flashing the ATtinys

Use of Visual Studio Code with PlatformIO or Arduino IDE

Praxisbeispiel: DIY Rubber Ducky with Digispark ATtiny85

My approach in the course

No (ok, only very few) slides/Powerpoint but more projects. We start in the basics immediately with a practical example. You can also try out the theory immediately with the ATtinys and thereby understand it better.

The practical projects are developed together in step-by-step instructions.

In this context, together means that I demonstrate the code, depending on the task, and you can follow the execution or rebuild your own way.

All codes are available for download on the platform, so you can get to the result without frustration.

No lengthy explanations or theory monologues, we start right away in the basics chapter.

Benefit from my years of experience and get the key skills in microcontroller development.

Get this course right now and you can start right away.

See you in class
