* Using the continuity setting on your multimeter, determine which is your Normally Open (N.O.) and which is your Normally Closed (N.C.) pushbutton switch. Building a simple switch and light bulb circuit, test out how each one behaves:

* Using With the ridiculous knife switch switches available in class, build a simple "selector switch" that turns on one of two bulbs:

* Build an AND gate and verify its behavior (by filling in the truth table):
** Which pins are the contacts that get switched?
** Is the relay Normally Open(NO) or Normally Closed (NC)?
** Using the multimeter for current sensing, how much current does the relay coil draw? * With the relay, build a simple S-R latch:

* Now, turn the latch into a pixel:
