Jumper Wire These wires are used with breadboard and development boards and are generally AWG solid core wire. Jumper wires can have male or female ends depending on how they need to be used.
To do this, a soldering iron is the tool you would use. You can choose leaded or lead-free solder in a few diameters. Electronic Components Now its time to talk about the different components that make your electronic projects come to life.
Below is a quick breakdown of the most common components and functions they perform. Switch Switches can come in many forms such as pushbutton, rocker, momentary and others. Their basic function is to interrupt electric current by turning a circuit on or off. Resistor Resistors are used to resist the flow of current or to control the voltage in a circuit.
The amount of resistance that a resistor offers is measured in Ohms. Variable Resistor Potentiometer A variable resistor is also known as a potentiometer. These components can be found in devices such as a light dimmer or volume control for a radio. When you turn the shaft of a potentiometer the resistance changes in the circuit.
These are often found in exterior lights that automatically turn on at dusk and off at dawn. Capacitor Capacitors store electricity and then discharges it back into the circuit when there is a drop in voltage.
A capacitor is like a rechargeable battery and can be charged and then discharged. Diode A diode allows electricity to flow in one direction and blocks it from flowing the opposite way.
Light-Emitting Diode LED A light-emitting diode is like a standard diode in the fact that electrical current only flows in one direction. The main difference is an LED will emit light when electricity flows through it.
Inside an LED there is an anode and cathode. The longer leg of the LED is the positive anode side.
Transistor Transistor are tiny switches that turn a current on or off when triggered by an electric signal. In addition to being a switch, it can also be used to amplify electronic signals.
A transistor is similar to a relay except with no moving parts. Relay A relay is an electrically operated switch that opens or closes when power is applied. Inside a relay is an electromagnet which controls a mechanical switch. This circuit contains electronic components like resistors and capacitors but on a much smaller scale. Integrated circuits come in different variations such as timers, voltage regulators, microcontrollers and many more.
What Is A Circuit? Before you design an electronic project, you need to know what a circuit is and how to create one properly.
An electronic circuit is a circular path of conductors by which electric current can flow. A closed circuit is like a circle because it starts and ends at the same point forming a complete loop. In contrast, if there is any break in the flow of electricity, this is known as an open circuit.
All circuits need to have three basic elements. These elements are a voltage source, conductive path and a load.
In practice, we have kilohm and megaohm units. Capacitors Capacitors are circuit elements that represent the opposite of resistors: They store electrical power.
Their capacity is measured in farads and practical subunits of a farad such as microfarad and picofarad. When arranged in parallel, their combined value increases. When in series, their combined value diminishes.
Basic electronics circuits always include some capacitors. Diodes and Transistors The diode, a circuit element, encourages current to flow in only one direction. It has two terminals, unlike the transistor—which has three. In the transistor, current can flow in more than one direction. Both diodes and transistors modulate current direction and voltage. Inductors, Transformers and RLC Circuit Basic electronics circuits often include inductors and transformers as circuit elements.
An inductor is a coil of wire that produces a desired magnetic field, unlike a capacitor, which produces a desired electric field.
Transformers, another type of circuit element, can step up a voltage or step it down to desired values. All these circuit components make up what is generally called "basic electronics.
