Exercise 5     555 Timer Design   Tune the 555 Timer circuit such that the frequency is 1 Hz +/- 50 mHz with a duty cycle between 30% and 70%.  Use only standard resistor values in your kits.  You can combine resistors in series.   Hand calculations will get you close and there are some online calculators that you can use to assist.  But some manual tuning may be needed.    Include a picture of the circuit, the component values used, and a screen capture of the results (Oscilloscope with frequency shown).  Leave the 555 Timer and Counter connected on your prototyping board, as we will use it later in the course.
