The first thine which you should know in building electrical circuits for an electrical device are basic theories in electronics. Know the different components used and how to connect them properly to each other. Then study how to read and make schematic diagrams which are graphical representations of an electrical circuit using symbols and images.
Doing so is essential when there is a particular device you want to make but is still confused with some parts of the process. This might be something a little advance such as voltage divider which produces an output that is a portion of its input. But learn or review first the theories in basic electronics to understand better the more advanced stuffs.
Begin with identifying the types of electricity such as AC or alternating current and DC or direct current. The direction which electrical signal flows on AC is constantly reversing or alternating with the reversal rate measured in Herts. Meanwhile the flow in DC is one direction to ground from power source and found commonly with batteries.
Circuit is closed if the path allows the electric current to pass through from a power source into the ground which usually indicates the device is turned on. An open one on the other hand breaks the path and would prevent movement such as when turning off machines. A switch is used in doing this so removing the source is not necessary when alternating between them.
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 can be done in two ways which are called series and parallel with the former indicating that all components are wired after the other. While the latter indicates that the parts are wired next to each other and which makes electricity pass them simultaneously. Both ways could be used in building your own circuits.
Resistors are used to add resistance into circuits and reducing their current flow with ohms used in measuring its different values. They have also wattage ratings and the colored bands surrounding their body indicates their resistance value. You can learn these colored bands or search for graphs which helps calculate their values instead.
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.
