Attiny13 Led Project

I’m trying to make a Christmas themed LED project using Attiny13.

But I have problems.

The code works differently when I run the same code with 3 batteries and 1 battery.In the code I wrote, the LEDs must first blink sequentially and then all together. The code works correctly [https://hizliresim.com/no3dqv8](First picture) with 3 batteries. But when I run the code with 1 battery [https://hizliresim.com/ghfc0i2](Second picture), only the 1st LED lights up and nothing else happens.

The same happens when I reduce the number of LEDs from 10 to 4. I was wondering if the battery was not strong enough.

Some people have made similar projects with more LEDs than this with 1 battery. What do you think is the problem? Hardware? Software?

Sounds like you’re not getting enough voltage under load.

Is your battery brand new?

If not, try a brand new battery and see if that works.
