LED Matrix Heart Animation ❤️ | Grow & Shrink with Arduino Uno | Arduino Tutorials

In this DIY Arduino project, I created a beautiful LED Matrix heart animation using an Arduino Uno and 74HC595 shift registers. The heart smoothly grows from small to big and then shrinks back to small, creating a simple but eye-catching LED effect. 💖 🔧 Components Used: • Arduino Uno • LED Matrix • 74HC595 Shift Register IC • Resistors • Jumper Wires • Breadboard • 5V Power Supply ⚡ How It Works: The Arduino Uno sends serial data to the 74HC595 shift register. The 74HC595 expands the Arduino's digital outputs and controls multiple LED rows or columns of the LED Matrix. The Arduino continuously changes the LED patterns to create the Growing & Shrinking Heart animation. By displaying different heart sizes in sequence, the LEDs create a smooth pulsing effect. ❤️ 💡 This project is a great example of how to use a 74HC595 shift register with Arduino to control multiple LEDs while saving Arduino GPIO pins. 👍 Like, Subscribe & Follow for more Arduino, IoT, Automation, Robotics, AI, LED Matrix, and DIY electronics projects!
