I need help in creating this circuit. It was given as my final year project for my foundation in electrical and electronic engineering by my lecturer. Every component seems to work perfectly fine especially when it is tested in sub circuits. The problem arises when I try to simulate the whole circuit the LEDs which each represent a number from one to sixteen just continuously switch on and off. I have attached the circuit diagram from which I am to recreate the circuit from. The circuit diagram is on page 3 and the components list is on page 4. The transformer, 230 A.C power source, IC6 , C3, C4, D17 and D18 are not going to be used as a powered bread board will be used as the power source.
