Step By Step Answers with Explanation
To design a Mod 10 counter using JK flip-flops with clock generation using a 555 timer and display the output on a seven-segment display, you'll need several components and follow these steps:
Components:
5. Resistors (for timing)
6. Capacitors (for filtering)
1. Clock Generation using 555 Timer:
- Use the 555 timer in astable mode to generate a 10 Hz clock signal with a 50% duty cycle.
2. Mod 10 Counter using JK Flip-Flops:
- You'll need two 74HCT112 dual JK flip-flops to create a Mod 10 counter.
- J2 = K2 = Q1 (output of the first flip-flop)
- Connect the clear (CLR) inputs of both flip-flops to ground (to disable the clear function).
- Connect the outputs of the 74LS47 to the corresponding inputs of the seven-segment display.
4. Display and Indicators:
- Connect the power supply to +5V and ground.
- Ensure proper decoupling capacitors for stable operation.
7. Adjustment:
- If the counter doesn't count correctly or the clock frequency is off, adjust the resistor values in the 555 timer circuit as needed.
