How to Choose a Microcontroller

1. I/O count — count pins needed; ATtiny for <8 I/O, ATmega for medium, STM32 for complex
2. Processing speed — 8-bit AVR (16MHz) for simple tasks; 32-bit STM32 (72MHz+) for heavy computation
3. Power budget — MSP430 for sub-1mA sleep current in battery applications
4. Toolchain — Arduino IDE (AVR), MPLAB (PIC), STM32CubeIDE (STM32)
