Hello all, I have a school project assignment where we are supposed to design a car that passes through stations and upon a passing through a selected number of stations, the car will automatically reverse. the car must be able to count the number of stations it passes on a HEX display and also count down when it reverses. the car must be able to stop upon hitting an emergency button in both directions we are provided with the following: 1) 74LS32 OR gate 2) 74LS08 AND gate 3) 74LS04 NOT gate 4) 74LS02 NOR gate 5) 74LS00 NAND gate 6) 74LS74 D flip flop 7) 2N3904 NPN transistor Light Dependent Sensor Circuit Counter and Display Circuit Motion Control Circuit Count Limiting Circuit (Need help with this!) I have already done the circuits above, all that is left is to create a count limiting circuit board that controls the count, whether the car moves forward or backward, basically it is the brain of the car. Appreciate any help rendered! Thanks!
