ATtiny microcontroller development for Arduino programmers

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 ATtinysUse of Visual Studio Code with PlatformIO or Arduino IDESet hardware configurations like CPU clock frequency, brown-out detection etc.Use of digital-analog GPIOs and PWM controlsPractical example: Digital dice with random number and LEDsPraPractical examplexisbeispiel: Digital dice with WS2812b and FastLEDPractical example: Binary clock with RTC Module and Shift RegisterPractical example: Plant monitor and Deepsleep with CR2032 BatteryPractical example: Plant monitor with OLEDPractical example: Tones (creating own Melody) as circuit board pendanPractical example: Transistor circuit with reedswitch and clap detectorPractical example: Temperature sensor with OLED 0,96” at Digispark ATtiny85Practical example: DIY Rubber Ducky with Digispark ATtiny85My 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
