The first thing that you should know when building circuits for electrical devices are the theories in basic electronics. Get to know the various components used in them and how to properly connect them to each other. And study how to make and read schematic diagrams that represents graphically the electrical circuit using images and symbols.
Doing so is important when you like to make a particular device but still confused on some parts of this process. This may be something a bit advance for you like the voltage divider which the output produced is a portion only of its input. Before tackling that, learn first or review the basic theories in electronics to better understand the advance stuffs.
Start with identifying the two types of electricity which are alternating current or AC and direct current or DC. The direction that electrical signals flows in AC is reversing constantly or alternating and the reversal rate is measured in Hertz. The flow in DC though is one direction from power source to ground and commonly found with batteries.
A closed circuit is when the electric current is allowed to pass through a path from power source to ground which normally indicates a device is functioning. While an open one breaks this path and will prevent the movement just like in turning off a machine. This is done with a switch so you could alternate between them instead of removing the source.
Components create resistance when current pass through them from positive voltage to ground and if these two are directly connected, it would cause a short circuit. This direct connection will result in explosion, fire, breaking or overheating which must be avoided. A switch would not add resistance so simply putting one without other parts is not advisable still.
Wiring things together could be done with two ways that are called series as well as parallel and the former indicating that every component is wired after each one. While the latter would indicate that the parts were wired next to the other which makes electricity simultaneously pass them. Both ways can be used together when you build circuits.
Resistors are used in adding resistance to circuits and reduce the current flow with them being available in different values measured in ohms. They also have wattage ratings and their value are indicated by the colored bands on their body. You may learn how to read these bands or just look up graphs that help you calculate their values.
Capacitors are components that stores electricity then discharges them when it drops and is measured in Farads with common ones being microfarad, nanofarad and picofarad. The commonly used types of capacitors are ceramic disc and electrolytic. The former being non polarized and the latter polarized requiring one of its leg to be properly connected with the power or ground.
Diodes are components that are polarized allowing one direction of passage for currents and causes a voltage drop as well. The side called cathode connects to the power and the opposite side is called anode. These are samples only of a few basic theories so research more about them.
