Im working on an led chaser circuit. I found it on many websites and chose the one which doesnt contain any 555 timer IC .. just a CMOS counter IC and a CMOS NAND gate to act as the oscillator.
Now. The problem is that the circuit was constructed exactly as described on the site aaroncake.com but it doesnt work. It uses a 9V battery and I used a fresh one. All the components were new. The LEDs were checked by the shopkeeper himself.
I dont know what might have gone wrong. Can anybody help me?
Thanks
