This week in class, we got familiar with a lot of components and terms in electronics, and saw examples of how to create circuit on a breadboard, started to build simple circuits and using multimeter.
↯ Sensors: translates signals from analog to digital. There are also actuators which translate digital to analog.
↯ Switches: Closing a circuit only when pressed/toggle/spin.
↯ Voltage regulator: 7805 regulator, translate input of 8-15V to output of 5V.
↯ LED’s are Diodes that emits light.
↯ Resistors: Resist the flow of electrical current
↯Beard-board: Tool for building circuits, and test it.
↯ DC Motor: An electromagnetic field generated by current flowing through a wire coil.
↯ Power jack: with a help from residents Ziv and John I manages to solder my own power jack! it was a fun little project by itself:
Current(I) – flow of electric charge, measured in Amps.
Voltage(V) – amount of energy to travel in circuit, measured in Volts.
Resistance(R) – used to control the flow of current. unit of electrical resistance is the ohm (Ω).
There are three formulas to get one of those variables:
V = I × R
I also found web site that can calculate this.
I started with setting up a breadboard, and used the power jack I soldered:
Arrangement of switches – three switches in parallel:
Three switches is series:
For my home work I decided to create a switch with a matchbox.
I started in trying to write to myself the schematic for it:
At first I wanted to create a switch that works from both sides of the box. But after spending a lot of time in soldering and creating the first LED, I decided to keep it one side.
I bought a coin battery of 3V, that way I could solder a circuit and put it inside the box:
