I have to built a Digital Stopwatch. i don't know how to make the connections between the particles (I don't know how to connect the pins pf the chips between them). If someone has a diagram or can help me with information about Digital Stopwatch send it please. I want actually the pinout diagram of the circuit. Below is the Block diagram of the stopwatch. I have to submit this project in 2 weeks from now.. So.....Help...
