I followed your instructions for toggle switch project but it doesn't seem to be working. The light ON's when it is powered up. I couldn't fine CD4017...instead i managed to get HCF4017BE.
Please advice.

Problem should be with circuit

Hi Maheshwaran, I have used both the CD4017 and the HCF4017 both have the same pinout and should work the same for your circuit as well. So there is no doubt that you have used the right IC.

The problem why you are not getting the output should be with your connectinos. Use a multimeter and try debugging it, it is hard to tell you where the problem is with the information you have provided
