📌 Simple project for beginners to better understand LED Matrix. I recommend trying it yourself.

Things you didn't know about Arduino!

☝️Arduino Uno is a controller based on the ATmega28 microcontroller, the platform consists of 14 inputs/outputs (6 of which are via PWM), 6 analog inputs, a 16MHz crystal oscillator, a USB port, a fast port, an ICSP port, and a reset button.

The word "Uno" means one in Italian. It's no coincidence that the creators of Arduino Uno tried to start a new era and a new flagship in the Arduino family of controllers with this new controller, and they succeeded. The reason is that Arduino Uno is much more compact, convenient, fast, simple, and of course cheaper than its other "brothers" in the Arduino family of controllers.

Briefly about Arduino Uno:
Microcontroller ATmega328
Operating voltage 5 V
Input voltage (recommended) 7-12 V
Input voltage (maximum) 6-20 V
Digital input/output 14 (6 of which are possible by KIM (Pulse Width Modulation)
Analog input 6
Current constant through input/output 40 mA
Current constant up to 50 mA for 3.3 Vk
Flash memory 32 KB (ATmega328) of which 0.5 KB is taken as a bootloader.
RAM 2 KB (ATmega328)
EEPROM 1 KB (ATmega328)
Frequency 16 MHz
In addition, the Arduino Uno device can be purchased from a USB or an organization source connected to it. In this case, if there are several sources, one of them is automatically selected.
The Arduino Uno controller is based on the ATmega328 microcontroller. This microcontroller has 32 kB of flash memory, of which 0.5 kB is reserved for the bootloader, in addition, 2 kB of RAM and 1 kB of EEPROM. Each of the 14 digital outputs can be configured as either input or output. This is done using the pinMode(), digitalWrite() and digitalRead() functions. Each output can drive a resistance of 20-50 kOhm and a current of up to 40 mA.

Building a Laser Security System | DIY Electronics Project

In this video, a laser security system is built using simple electronic components. The system is designed to detect intrusions by interrupting a laser beam, which causes an alarm to be triggered. This method can be used for DIY home security or for learning about laser-based sensors.

My 8-Bit Computer Runs Simple Animation Program

I found an interesting video about building a computer inside of a game. It is Minecraft. Yes, there are people who built Minecraft inside of the Minecraft. I mean that's so incredible — the amount of time, effort, and dedication. It took them 7 months to accomplish. That's so crazy guys!

I wanna share it with you😅

Enjoy the video and get inspired to build your own 8 bit computer. But with microcontroller not Minecraft 😅

On March 3rd, our JS Robotics Team participated in one of Uzbekistan’s largest robotics contests for high school students— "Ixtirochilikka Qadam 2025."

We presented our improved Autonomous Hydroponics, a self-regulating, soil-free agricultural system that integrates sensor-driven environmental control, automated nutrient management, and adaptive lighting to optimize plant growth with minimal human intervention.

Competing in the Regional Stage (3rd round), we faced strong competition from 46 schools across the Jizzakh Region. We successfully passed with 89 points, securing 1st place and earning a ticket to the Republican Stage! 🎉

Additionally, we received $1,200 in funding to further develop our prototype and make it even more competitive for the final stage. Over the next two months, we will be integrating new sensors and components to expand its functions and capabilities.

Wish us luck! 🚀

📸 Check out some highlights from the competition day!
📢 In our next post, we’ll dive deeper into the project itself.
