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.
A circuit is closed when electric current is being allowed passage through a path to ground from power source which indicates a functioning device normally. While the open one has broken the path and prevents movement when a machine is turned off. This is done using a switch so you can alternate between them rather than removing its source.
Components creates resistance if current pass through from a positive voltage to a ground and a short circuit happens when these two are connected directly. Avoid this direct connections because they would result in breaking, overheating, explosion or fire. Putting only a switch between them is not enough and other parts are needed for additional resistance.
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.
Adding resistance into circuits is done with resistors and they reduce current flow and are also available in a variety of values measured with ohms. They have wattage ratings also and their value is indicated by colored bands around their body. You could learn reading these bands or look up for graphs that helps in calculating 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.
