Hello. I have been working with microcontrollers for years and I know them very well. I like to use Proteus because I think it is one of the best environments to work on. I know how frustating can be when the circuits don't work as we want them to, so I am here to help you with your issue. I have done these digital clocks several times, so I know what I am talking about. If you decide to accept this offer, don't hesitate to contact me so we can talk about this project and start right away to get it done as soon as possible. Best regards. David Nery

Hi, I have about 9 years of experience in various circuit design and PCB development. I would propose to have a look at the circuit diagrams to see if there is any fault. If there is no fault it might be required to inspect the PCB layout.
