💡 Arduino Back-and-Forth LED Flasher Here's a simple Arduino project that's perfect for beginners — a row of LEDs that chase from one side to the other, then reverse direction and come back. ➡️ 💡 💡 💡 💡 💡 ⬅️ 💡 💡 💡 💡 💡 Simple project? Absolutely. But there's a lot we can learn from it: 🔌 Wiring LEDs correctly 📐 Choosing current-limiting resistors 🤖 Arduino digital outputs 💻 Using loops in Arduino code ⏱️ Controlling timing with delays 🔍 Troubleshooting when an LED doesn't behave correctly And once the basic version works, we can make it more interesting — change the speed, add more LEDs, create different patterns, or control it with a potentiometer.
