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
- Set hardware configurations like CPU clock frequency, brown-out detection etc.
- Use of digital-analog GPIOs and PWM controls
- Practical example: Digital dice with random number and LEDs
- Practical example: Digital dice with WS2812b and FastLED
- Practical example: Binary clock with RTC Module and Shift Register
- Practical example: Plant monitor and Deepsleep with CR2032 Battery
- Practical example: Plant monitor with OLED
- Practical example: Tones (creating own Melody) as circuit board pendan
- Practical example: Transistor circuit with reedswitch and clap detector
- Practical example: Temperature sensor with OLED 0,96” at Digispark ATtiny85
- Practical example: 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.

Who this course is for
- Anyone who wants to deepen their knowledge of low-power, small form factor microcontrollers.
- Developers who are interested in using low-cost microcontrollers for their projects.
- All those who want to understand, apply and write their own practical projects with microcontrollers.
- All those who want to learn more about microcontrollers with limited hardware resources.
- Excellent course. I was interested in the ATTiny controllers and was looking to understand how to use them. The instructor has provided a good introduction to the ATTiny controllers and has provided good tips e.g. the fuse settings. I now have a good understanding of how to use the ATTiny controllers ~ Joydeep R
- Good content and easy to follow ~ Arthur O
- The instructor presents concepts and important real world points that are important. The parts have gone up in price. My $2.00 ATTiny85 chips (Dip verion) now cost over $5 on Amazon. Small boards, however, are available. They include a USB connector and a voltage regulator. Everything is SMT. This course will get everyone quickly developing ATTiny projects ~ Michael T
