Blue LED ciruit
I am attempting to make this device pictured here.
I am looking for someone with a knowledge of LED circuits to help me develop the board used to power the 6 flashing blue LEDs which, when first switched on has LED number 1 lit, then when a non-locking button is pushed the 2nd LED lights and flashes with the first still lit and flashing, and so on until all 6 LEDs are lit. When finally the non-locking switch is pushed all 6 LEDs are switched off?
Is this possible.
I'm new here and would appreciate any help you could offer.
