# Microcontrollers # Microcontrollers are widely applicable to most applications requiring real-time processing and low cost. We are most familiar with the ESP32 series of microcontrollers and Arduino IDE, and have 12+ videos on the topic; [here](https://www.youtube.com/watch?v=pNDzUEHkqHs) is a recent example before we shifted our focus to projects using more powerful MCUs, like the 8x17mm STM32H5 module covered towards the end of [this video](https://www.youtube.com/watch?v=EQ1ZQpfELaQ). ![[pcbexample.jpg]] *Example design: ESP32 home automation hub optimised for ultra-low power operation* To do: - Complete more advanced STM32 projects with U3B5/C5 series, N6 series, and V8 series - Demonstrate deeper knowledge of internal MCU hardware within code - Expand into different MCUs such as RA series and CH32 series - Learn more about local video and audio processing - Expand into more FPGAs and MPUs (yes, they aren't microcontrollers but still worth putting here for now) to enhance understanding of processor logic
