What is the smallest board I can use to run a very simple project to slowly flash 5 LEDs ?
I need to run from a small battery.

Arduino Nano Every
Arduino Nano Every is a compact, low-cost microcontroller board ideal for beginners and makers, offering versatile performance for embedded and prototyping projects.
The D1 Mini is a great choice for your project. It's very compact — just 34.2mm × 25.6mm, so it fits easily even in tight spaces. It can handle 5 LEDs without any issue and works well with small batteries, especially if you use sleep modes to save power.
Price-wise, it's quite affordable too — usually around ₹160–₹230 from local electronics shops, and about ₹350–₹500 if you're buying it online from sites like Amazon or Flipkart.
