I have a problem with my scheme is not working as it was thought that the scheme is flashing LEDs and a button shoulda turn on all lights, but does not work, work only when the diode is lit first, then I have a question where the problem is that the button does not work and other diodes?! thanks
p.s I use Proteus ISIS 7 profesional for the establishment of the scheme and AVR Studi 4 for the code-writing
