Create a mesmerizing LED chaser, which sequentially lights up a row of LEDs.
Materials Needed:
1. Arduino Uno
2. Breadboard
3. 8 LEDs (any color)
5. Jumper wires
Circuit Diagram:
1. Connect the positive (longer) leg of each LED to a digital pin on the Arduino (pins 2 to 9).
2. Connect the negative (shorter) leg of each LED to a resistor (220 ohms).
3. Connect the other end of each resistor to the ground rail on the breadboard.
4. Connect the ground rail on the breadboard to one of the GND pins on the Arduino.
Step-by-Step Instructions:
1. Setup the Breadboard:
Place the 8 LEDs on the breadboard.
Connect one end of each resistor to the negative leg of the corresponding LED.
Connect the other end of each resistor to the ground rail of the breadboard.
2. Wiring the LEDs to the Arduino:
Connect the positive leg of each LED to the Arduino pins (2 to 9) using jumper wires.
Connect the ground rail of the breadboard to one of the GND pins on the Arduino.
3. Upload the Code:*
Open the Arduino IDE on your computer.
Copy and paste the provided code into the IDE.
Connect your Arduino to the computer using a USB cable.
Select the correct board and port from the Tools menu.
Click the upload button to transfer the code to the Arduino.
4. Power the Arduino:
Once the code is uploaded, the Arduino will automatically start running the LED chaser effect.
If you want to power the Arduino independently, you can use an external power source or battery pack.
5. Enjoy the LED Chaser Effect:
Watch the LEDs light up sequentially, creating a chasing effect.
Adjust the delay value in the code to change the speed of the chase.
Tips:
Experiment with different numbers of LEDs and pin configurations.
Customize the delay times to create unique lighting patterns.
Integrate the LED chaser into other projects, such as decorative lighting or visual indicators.
Conclusion:
This Arduino LED chaser project is a great way to learn about basic electronics, programming, and creating dynamic visual effects. It's perfect for beginners and can be expanded into more complex projects with additional components and coding.
