I wanted to do a simple project using a photoresistor and LEDs.
That gave me the idea of this project. It uses the photocell to turn on LEDs.The project:
I started to think of a little circuit but it didn't work so I included the 74HC595 monitor.
This module add pins to the AtMega. It's useful when you need pins which aren't present on your card.
I used it to command all the LEDs. It can also be used in a lot of ways.
Afterwards, I did the program. I had to do some research to know how to code the module but finally, I did it.
And that's how I made this project.
P.S.:If you want more informations, please ask me in the comments and explain it. And please respect my project.
