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.
It is important to do so when you want to make a certain device but are confused still with some parts concerning the process. Voltage divider is an example of an advanced topic which the produced output is only a portion of what its input is. But first, learn or review the theories on basic electronics and understand the advance stuffs better.
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.
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 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 which stores electricity then when it drops, discharges them and Farads is used to measure them with common units being picofarad, microfarad, and nanofarad. The capacitor types most used commonly are ceramic disc as well as electrolytic. The former is non polarized while the latter is polarized needing one leg to properly connect with the corresponding one.
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.
