“This project is a logic puzzle for the festive season in which the aim is to get all five LEDs to stay lit up.
On the Technoblogy website, there is a project called the “Five LEDs Puzzle”. Basically the challenge is to work out what sequence of switches need to be pressed to light up five LEDs. Although I think I figured out the sequence by following the code, I really needed to build it to see if it was correct.
I decided to use a cheaper ATtiny13A microprocessor since the ATtiny85 seemed a bit of an overkill for this project. I prefer to make my own circuit boards rather than use protoboard or breadboards. The Eagle files have been included should you wish to get the board commercially made or do as I did and make it yourself. I used the Toner method.”
