Crystal Clear Electronics mobile app

In the CCE mobile app you can find everything that helps you to begin your study: written and video lessons, numerous additional material and tools and components lists. We created the mobile app to make it easier for you to grasp and master electronics, whether you're traveling or just have a few spare minutes.

You can download the mobile app to your Android or iOS device from Google Play or the App Store under the name Crystal Clear Electronics.

Still life in the Crystal Clear Electronics studio

We set up the Crystal Clear Electronics studio in 2023 to film our electronics based video series. In 2024 we redesigned the whole set for the CCE2 videos.

The sets of the videos feature many electronic components. Which one was your favourite?

The history of the STM32 microcontroller family

The STM32 microcontroller family was launched in 2007 with the STM32F1 series, which was based on the ARM Cortex-M3 core. Even the first model stood out with its performance, low power consumption, and advanced peripherals. Later, ST developed the family in different directions: inexpensive, industrial, and low-power versions also appeared, covering a wide range of the market.

The STM32F4 series broke new ground in 2011 with the Cortex-M4 core and floating-point unit. The L and H series focused on energy efficiency and high performance, respectively. Newer types, such as the G, U, WB, and WL series, opened up the world of IoT, security, and wireless communication. The STM32MP1 already runs Linux, forming a bridge between the worlds of MCUs and MPUs. Today, STM32 is one of the widest and most versatile microcontroller platforms, from hobby electronics to industrial systems.

If you want to learn more about STM32 microcontrollers, we recommend the videos in chapters 1 and 2 of CCE2!

The STM32 microcontroller is one of the most popular and versatile platforms in the world of embedded systems. Developed by STMicroelectronics, it has become a cornerstone of professional development thanks to its performance, energy efficiency, and flexibility.

But what is the STM32 good for?

💡 Industrial automation: motor control, sensor data processing, machine and robot control.

🏠 Smart home systems: managing temperature, light, or motion sensors, and energy management.

🚗 Automotive applications: development of safety systems, communication modules, and onboard electronics.

📡 IoT devices: wireless sensor networks, data acquisition units, real-time data processing.

🎮 Interactive projects and prototypes: displays, touch sensors, audio processing, or even controlling robotic arms.

The wide range of the STM32 family allows you to create anything from simple hobby projects to complex industrial systems.

Crystal Clear Electronics 2 is a practical curriculum that, using a Nucleo development board, demonstrates step by step how the STM32 microcontroller works — from handling peripherals to building independent, real-time applications.

You won’t just learn how to program; you’ll understand how software and hardware communicate deep within the technology.

If you’re curious about how smart devices, IoT systems, or industrial controllers are built, learning STM32 opens the door to the world of modern technology.

Crystal Clear Electronics Summer Camp 2025

Two weeks ago, the CCE summer camp came to an end, where students completed exciting project tasks.

In the beginner group, building on the CCE2 curriculum and videos, students were able to create various simpler games, such as the "Pong"-inspired programs shown in the video below, but we also saw some unique applications, such as a slot machine or a shooting gallery.
The advanced group was creating a navigation device, which we implemented using a unique circuit. Before the summer camp, the students attended the Crystal Clear Electronics extracurricular activities weekly, where they acquired the basic knowledge necessary to program the unique circuit, containing a GPS and IMU unit.

If you would like to try out the advanced group's project, you can find the necessary description, example programs, and components on the Crystal Clear Electronics 2 website at the following link:

We have translated the CCE videos into five additional languages with the help of AI

At our multiplier events throughout Europe, we encountered two phenomena: teachers prefer teaching materials that are available in their native language, and with the spread of AI, they are eager to take advantage of its benefits. We decided to use AI to translate our video materials into additional languages: German, Italian, Spanish, French, and Japanese.

Fortunately, even AI is not perfect. 😊

Due to possible bugs and technical inaccuracies, we still recommend our English and Hungarian videos to those who are interested. We hope that this small innovation will be useful to many of you!

You can access the playlists in different languages on our YouTube channel:

We make electronics teaching materials starting from the basics, to more advanced 32-bit microcontroller programming. Follow our YouTube channel and become the electronics expert of the future!
