Hello! I'm currently in a school project assignment where we are supposed to design a car that passes through stations and upon a passing through 8 of stations, the car will automatically reverse. The car must be able to count the total number of 8 stations, then it passes on to 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. I am stuck with the forward and backward signal. We can tap the CLK signal from The Light Dependent Sensor Circuit and also Q0-Q4. I wonder is there any clues for making the signal because my group have tapped Q4 into a multiplexer (74LS157) A/B toggle but the 7-segment can only count from 0-7 and 7-0, not 8. We need to display 8. Thanks!
