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.
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.
When current pass through components, they create resistance to ground from positive voltage and if these are directly connected, this would cause the circuit to be shorted. This direct connection would result in fire, breaking, overheating or explosion which you must avoid. Putting switch would not provide additional resistance so other parts must be added.
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 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.
Components which stores electricity and discharges them when they drop are called capacitors and is measured with Farads commonly shown in units of nanofarad, picofarad and microfarad. The types of capacitors commonly used are electrolytic and ceramic disc. The latter being non polarized while the former is polarized requiring one leg to connect properly with either the ground or power.
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.
