Build a circuit using a circuit diagram. Make a closed loop using a light bulb. Purchase a kit for practice projects. Practice working with Arduino boards. Build circuits using a breadboard. Make your own projects with online schematics.
Search for circuit diagrams online to find a few simple ones you can attempt to build on your own. Read the diagram to figure out what components you need. Then, build the circuit so it looks like the diagram. It will help give you an idea of how a circuit works. It is best to start with a smaller circuit. Pick one with few branching lines and available components like a battery and light bulb. Gather 2 copper wires, a fresh battery, and a light bulb. Set the components on a table, then hold the wires to connect the battery terminals to the bulb’s metal base until the light bulb lights up.  You can light the bulb with only these components. The electrical current flows from the negative terminal to the positive one, passing through the light bulb along the way. Seeing this closed loop make your light bulb come to life can give you a better understanding of how electricity moves in a circuit. Go online to find a variety of beginner kits for electronics. There are a wide variety of kits available, each one packaged with the parts to complete a simple product. This is a good way to begin learning about electronics without building your own circuit board. For example, an educational rover is a small, pre-built robot. It is used to learn some basic customization and programming techniques. Arduino boards are inexpensive circuit boards used in most electronic projects. These are included in any kits you buy, but you can also purchase them separately online. They are beginner-friendly, so try using one to build some basic circuits and projects.  A typical starter project is the “blinking light,” which teaches you how to make an LED light blink with some simple Arduino programming on your computer. If you don’t want to purchase a kit, you can get started with an Arduino board and a USB cable. Connect the board to your computer and download the Arduino software online. A breadboard is a way to build a circuit without soldering. It looks like a piece of plastic with a bunch of holes in it. Push the wires into the holes to connect them in a circuit. Connect the wires to an Arduino board or battery to create an electrical current. Try activating an LED light using the breadboard. You will need wire, an LED, a resistor, and an Arduino board.. All of these parts can be ordered online. Once you are comfortable building circuits, come up with a few projects you would like to make, such as an alarm or sensor. Schematics are design diagrams that show you how to build a project. Many schematics can be found by searching online. For example, type “blinking light schematic” to find a few ways to build a circuit with an blinking LED light.
