Activity 1.2.7
Introduction
The field of analog electronics is a unique discipline, distinct from the study of digital electronics. We have only scratched the surface of what you would learn if you continued your studies in this area. This project will be the last activity in our brief journey into the world of analog electronics.
In this activity you will use the Circuit Design Software to build and test the complete analog section of the Board Game Counter design.
Equipment
· Paper & pencil
· Circuit Design Software (CDS)

Conclusion
1. When you press the push button of the Board Game Counter, the 555 Timer oscillates at approximately 65 Hz. It you want the oscillation to start at 100Hz, what value would you apply to C2?
Approximately 290nF
2. The values of R8 & C1 determine the time from when the push button is released to when the oscillation stops. If you wanted to lengthen this time period, what changes would you make to one or both of these components? Explain.
If you wanted to lengthen this time period you would lower the resistor and increase the power of the capacitor
