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 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.
Start by identifying the two kinds of electricity that are direct current and alternating current which are also known as DC and AC respectively. In AC, the direction where the electrical signal flows is alternating or reversing constantly with Hertz used to measure the reversal rate. In DC though, the movement is one directional from power source, commonly batteries, into the ground.
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 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 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.
