I have been directed to use logic to operate a carpark. The Park can hold up to 48 cars. When there are 40 the barrier for in will go down and let cars in individually up to the 48. if the barrier is down there is a red light. Sensors are present to say when a vehicle enters and leaves. I am struggling where to start with this would 2 74ls192's be a good start and could you give me any other tips.....
Thank you in advance Les
