MY DOCUMENTATION

Day 1 (13.06.14)

Important terms:

  • DC – Direct Current (постоянный ток)
  • AC –Alternating Current (переменный ток)
  • С - Capacitor (конденсатор)
  • R – Resistance (сопротивление)
  • F – Farad (Фарад)
  • LEDLight-emitting diode – Light Emitting Diode (светодиод)


Types of Resistors:

  • 1K Ohm – brown/black/red
  • 10K Ohm – brown/black/orange
  • 100K Ohm - brown/black/yellow
  • 1MEG Ohm - brown/black/green


Resistance can be in series and parallel.

1 LEDLight-emitting diode
3 LEDLight-emitting diode in series
3 LEDLight-emitting diode in parallel

Day 2 (14.06.14)

Types of Switches (ключ – переключатель/включатель):

  • SPST – Single Pole Single Throw
  • SPDT – Single Pole Double Throw
  • DPDT – Double Pole Double Throw
  • Tilt Switch
  • Rotary Switch


H-Bridge (H-Мост) – in that circuit motor can change directions with the switch.

ASSIGNMENT

So I chose to do Assignment 2 - "Variable Resistance"

The first idea that came to my mind was to use pickles, because they are very good conductors.

In the beginning of developing that idea, I did a few tests to see how it will work with one or two pickles.

So to the both ends of the alligator clips I attached needles, and then I was poking with them my pickles to see which sounds it will give me. While I was testing, I did some changes for the size of the resistance and capacitors.

During the open lab on Thursday, I got some important tips from Darsha Hewitt on how I can develop my work. And also the same day I got to knew about circuit with two 555 Timers. And I decided to use that for more interesting sounds in my work.
