January 27 and the Chip 555

on thursday january 27 we worked with a very interesting chip, chip 555 timer.
we used the chip in some various settings. What the chip does is basically controlling the output signals when the values change for capacitors and resistors. first we made a board that by control of the chip made a LED flash periodically.  Then we used the chip to control the sound coming out of this speaker.

and after that we connected our boards to an oscilloscope to see the difference in amplitude and and wavelength of a signal when we change the values of capacitors or resistors.
