Hi all, Would need your expertise to start off with this project. I had got a project whereby its a card that come with a preloaded values of 10 units. The card will cause the LED to light up. However, if the units in the card is less than 3, another LED (A) will light up to inform insufficient units left. if the units in the card is zero, another LED (B) will light up to inform of no units left when the two LED (A) and (B) light up, there will be a TOP_UP input (implemented by pushbutton switch) to set the units back to 10. The LED will light up for only one clock period. I was given 2 to 1 multiplexer, flip flops, synchronous 4-bit up/down counter with dual clock and other TTL integrated ciruit components. How can I start with the design? Thank you for your guidance.
