You are asked to learn how to create a square wave $($on$,$ off, on$,...)$ and control the frequency. It is not critical that it be accurate to

$1$ part in a million, as it is for watches.

As a hint, mechanical clocks use an element that tends to oscillate at a particular frequency. The pendulum in a grandfather clock, for example. Since it loses energy to friction, a complicated mechanism has to keep "pushing" the pendulum so it doesn't stop, but the length of the pendulum is what keeps the time stable.

Research a similar solution using the $555$ timer chip. In class, we will be reviewing RC circuits, which will help you to understand the timing element.

The purpose of this homework is for you to take the time to look it up$,$ get a schematic online, draw it in your CAD package in advance, and calculate exactly what parts you need. Then, in lab you can build it$,$ having hopefully figured out in advance some of the issues you might face.

Create a schematic, and a description showing that you know how to compute the right values for resistors and capacitors to control the timing
