1. ELECTRONIC PRODUCTS ASSEMBLY & SERVICING LESSON 3: BREADBOARD CIRCUITS

2. BREADBOARD sometimes called a plugblock is used for building temporary circuits. It is useful to designers because it allows components to be removed and replaced easily. It is useful to the person who wants to build a circuit to demonstrate its action, then to reuse the components in another circuit.

3. HISTORY OF BREADBOARD ELECTRONIC PRODUCTS ASSEMBLY & SERVICING ELECTRONIC PRODUCTS ASSEMBLY & SERVICING

4. HISTORY Breadboards have a captivating history that dates back to the early days of electronics. The name “ breadboard ” originated from a time when people would actually use wooden bread cutting boards to build their electronic circuits. They would place components like resistors, capacitors, and transistors on the wooden surface and connect them with wires.

5. HISTORY

6. HISTORY The modern breadboard, made of plastic and metal , was invented in the 1960s . It was designed to provide a reusable platform for rapid prototyping and testing of electronic circuits. Since then, breadboards have become an essential tool for electronics hobbyists, students, and professionals.

8. HOW BREADBOARD WORKS ELECTRONIC PRODUCTS ASSEMBLY & SERVICING ELECTRONIC PRODUCTS ASSEMBLY & SERVICING

9. HOW IT WORKS ? Breadboards are rectangular boards featuring a grid of small holes. Beneath the surface, metal strips connect these holes in a specific pattern, allowing components to be electrically connected without the need for soldering. The holes are typically spaced 0.1 inches apart , which is the standard spacing for most electronic components.

10. HOW IT WORKS ? To create a circuit, simply insert the leads of your electronic components, such as resistors, capacitors, and integrated circuits, into the holes on the breadboard. The metal strips underneath create the connections necessary for your circuit to function.

13. BREADBOARD POWER SUPPLY The Breadboard Plug-in Power Supply Module is a device that provides regulated voltage rails for project circuits on a solderless breadboard. It can be powered using an input voltage range of 6.5 Volts to 12 Volts . The module has two voltage regulators which output 3.3 Volts and 5 Volts .

14. JUMPER WIRES Jumper wires are wires that are used to make connections on a breadboard. They have stiff ends that are easy to push into the breadboard holes. Also, it has two types of head shapes: square head and round head.

15. JUMPER WIRES There are several different options type of jumper wires. Male-to-Male Jumper Wire Male-to-Female Jumper Wire Female-to-Female Jumper Wire

16. JUMPER WIRES The difference between each is in the endpoint of the wire. Male ends have a pin protruding and can plug into things, while female ends do not but are also used for plugging. Moreover, a male connector is referred to as a plug and has a solid pin for center conduction . Meanwhile, a female connector is referred to as a jack and has a center conductor with a hole in it to accept the male pin.

18. SOLID-CORE HOOKUP WIRE Although this has the same usage as the Jumper Wire, this is much easier to use as you can customized the length of the wire. You may also purchase a fixed Hookup Wires as this will give you more options and less time to cut the wire yourself. Also, this is only available as your substitute male to male wire.

19. RESISTOR The resistor moderates the flow of electrons , so the current doesn't move too quickly and cause damage to the breadboard, wires, battery, etc. The second reason to use a resistor is to slow the current flow to a component.

20. LED LIGHT The term LED is an abbreviation for Light Emitting Diode . When current flows through an LED, it emits light. It glows more brightly with more current, and less brightly with less current. That takes care of “light emitting”,

21. A diode is a one-way valve for electric current. In other words, current can only flow through in one direction. If the pins are reversed, no current will flow, and the LED will not emit light. The longer (+) pin is called the anode and the shorter one is the cathode. LED LIGHT

22. BREADBOARD sometimes called a plugblock is used for building temporary circuits. It is useful to designers because it allows components to be removed and replaced easily. It is useful to the person who wants to build a circuit to demonstrate its action, then to reuse the components in another circuit.

23. PARTS OF BREADBOARD Breadboard have three parts: Power Rails: These are the rows of holes running along the top and bottom of the breadboard, usually marked by red and blue lines. The red line represents the positive voltage supply, while the blue line represents the ground or negative voltage.

24. PARTS OF BREADBOARD Terminal Strips: These are the rows of holes in the middle of the breadboard. They’re used to connect individual components, forming the primary part of your circuit.

26. PARTS OF BREADBOARD Bus Strips: Some breadboards have extra columns, called bus strips, which can be used to distribute power, ground, or other common signals.

28. WHY DO WE NEED TO UNDERSTAND HOW TO BREADBOARD WORKS? ELECTRONIC PRODUCTS ASSEMBLY & SERVICING ELECTRONIC PRODUCTS ASSEMBLY & SERVICING

29. WHY Understanding Hardware Prototyping: Understanding how a breadboard works is essential for senior high school students as it bridges the gap between theory and practical application in electronics. By using breadboards, students gain hands-on experience, reinforcing concepts like voltage and current while developing critical thinking and problem-solving skills.

30. WHY This foundational knowledge prepares them for advanced studies in engineering and technology, fostering creativity and innovation as they experiment with different circuit designs. Additionally, working with breadboards enhances practical skills relevant to modern technology and encourages collaboration, making it a valuable tool for both education and future career paths.

31. WHY Collaboration with Hardware Engineers: In the ICT Industry, IT professionals often collaborate with hardware engineers. Understanding breadboarding allows IT students to communicate effectively with hardware engineers, facilitating teamwork and project collaboration.

32. WHY Pursuing different field as Advanced Studies: For IT Students who take interest in pursuing different field s, this will help you to start up your understanding embedded systems, robotics, or hardware-centric IT specializations, proficiency in breadboarding serves as a foundational skill.

33. WHY Integration with Software: Many IT projects require integration between hardware and software components. Knowing how to use a breadboard allows students to interface hardware components with software applications they develop, providing a deeper understanding of how the two interact.
