Here is a simple DIY project that makes a cool LED flasher circuit. Check out this site for more information including full schematics and other diagrams.
“Five pins from RA0 to RA4 are used as the input pin.
These pins are pull-uped with 10K ohm resisters. So, when a switch isn’t pushed, the input becomes H level ( +5V ). and when a switch is pushed, it will become L level ( 0V ). When the switch closes, the chattering occurs. The chattering is the phenomenon which occurs with the bound of the point of contact. The opening and shutting of a point of contact is repeated in short time..
I don’t put the prevention circuit of the chattering at the circuit this time. When the software detects that the switch is closed once, the blink processing of LEDs are executed in the time which is longer than the chattering.”

Hello,
Is it posible to order the chip IC1, progrmed and sent too Belgium?
What is the price of it?
Thank

I like pattern 5…how would you make it light the first led, and each one in sequence after that keeping the all the previous ones lit?…once it gets to the last one, they’d all go off.

That’s pretty cool! There’s a similar lighting kit on this site: http://www.lifelites.com Looks like that one has 2 buttons and 8 sequences. I was thinking about trying to make one myself. Thanks for posting!

this is the only circuit that I have seen very simplest flasher can create various flashing systems.Thousand thanks you to show
us this circuit.
