Also you need to learn how to clean up your breadboard to help you find faults... The zener diodes are not connected to the 555 timer like in the schematic and also need to connect to pin 14 on the clock chip instead of pin 15..I am very grateful for your reply but I am a complete novice. I really don't know where those holes are. There's nothing connected to hole 30. In the picture the breadboard is inverted.
Could you point this out for me? I'm sorry for being so stupid.
Thanks a lot.
