The 555 Timer
Description
The 555 Timer oscillator is one of the most common circuits used in introductory electronics. It is a favorite among beginners because of its low cost and ease of design. These are precisely the same reasons the 555 Timer is used in the Board Game Counter design. In this activity you will simulate and build a 555 Timer oscillator. You will observe the effect that varying the value of its resistor and capacitor values has on the oscillation frequency and duty cycle.
Conclusion Questions
1. The higher the RA was raised, the frequency was decreased. Duty cycle continued to rise.
2. The higher the RB was raised, the frequency and duty cycle was decreased.
3. The lower the C was changed, the higher the frequency. Duty cycle took no effect.
