The term \u201cBreadboard\u201d comes from a literal piece of wood used to cut bread, which, back in the early days, people would build electronic circuits on it. A typical circuit is seen in the picture above.<\/p>\n\n\n\n
However, with the years of evolution comes design changes. Now, thanks to the invention by Ronald J. Portugal, the breadboard we know comes in a smaller, more portable white plastic and pluggable design.<\/p>\n\n\n\n
Grove Base Shield can play the role of breadboard while its plug-and-play design enables a more convenient using experience. <\/strong>Grove Base Shield provides a more simple way to connect with Arduino boards and helps you get rid of breadboard and jumper wires! <\/strong>You can directly connect grove sensors to the Base shield through Grove Cables. <\/p>\n\n\n\n About Grove System<\/strong><\/a><\/p>\n\n\n\n Grove is a modular, standardized connector prototyping system. Grove takes a building block approach to assembling electronics. Compared to the jumper or solder-based system, it is easier to connect, experiment, build, and simplify the learning system. <\/p>\n\n\n\n We\u2019ve seen the type of breadboard originating in the past, but the modern-day solderless breadboard comes in different types; full-sized, Full+, half-sized, Half+, and mini.<\/p>\n\n\n\n If there’s no Grove connector on your board, you need a Grove Expansion Board<\/strong> to attach the Grove modules. The Grove Expansion Board provides the processing power, and the modules offer your system’s input sensors and output actuators. There are many Grove Expansion Boards for different platforms already, they include Arduino UNO, Particle Phone, BeagleBone board, etc.<\/p>\n\n\n\n Arduino Uno is the most popular Arduino board so far, however, it is sometimes frustrating when your project requires a lot of sensors or LEDs, and your jumper wires are in a mess. Base Shield provides a simple way to connect with Arduino boards and helps you get rid of breadboard and jumper wires.<\/strong> With the 16 on-board Grove Connectors, you can easily connect with over 300 Grove modules! <\/strong>Apart from the rich Grove connectors on the board, you can also see an RST button, a green LED to indicate power status. The pinout of Base Shield V2 is the same as Arduino Uno R3.<\/p>\n\n\n\n Grove Shield for Raspberry Pi Zero is an expansion board for Raspberry Pi Zero<\/strong>, designed by Seeed Studio, for the orderliness of your connected sensors when you develop projects with Pi Zero. It maintains 24-Pin GPIO and provides 15 additional Grove ports based on the MM32 chip, along with other interfaces, giving you a great and quick development experience.<\/p>\n\n\n\n Mega Shield is an extension board for Arduino Mega and Google ADK. We have standardized all the connectors into 4 pins (Signal 1, Signal 2, VCC, and GND) 2mm connectors and kept some of the 3pin (Signal, VCC, and GND) 2.54mm headers for Servo and Electronic Bricks, which simplify the wiring of electronics projects. The 4pins buckled connectors also make the wiring situation more stable. The Mega Shield includes Digital 0 – 21 and Analog 0 – 15; We abandon Digital 22 – 53 for easily installing Mega Shield with Xduino Mega\/Google ADK.<\/p>\n\n\n\n Grove Shield for Raspberry Pi is an expansion board for Raspberry Pi<\/strong>, designed by Seeed Studio, for the orderliness of your connected sensors when you develop projects with Pi. It maintains 24-Pin GPIO and provides 15 additional Grove ports based on the MM32 chip, along with other interfaces, giving you a great and quick development experience.<\/p>\n\n\n\n This shield is a plug-and-play Grove extension board for Seeed Studio XIAO. It helps to get rid of jumper wires and soldering work by pulling out the pins of the Seeed Studio XIAO and expanding to 8 Grove connectors, including two Grove IICs and one UART. It acts as a bridge between Seeed Studio XIAO and Seeed’s Grove system, which includes 300+ Grove<\/a> modules. No more jumper wires and soldering work, you can enjoy creating more projects with Seeed Studio XIAO easily and quickly.<\/p>\n\n\n\n When you first lay your hands on a breadboard, you\u2019ll find that there are many pinholes and start to wonder how do I start connecting things? Before you get started, you should learn about the parts and how to power a breadboard.<\/p>\n\n\n\n A breadboard consists of two areas called strips: the bus and terminal strip.<\/p>\n\n\n\n Note: Although each row has 10 pinholes, you can only connect 5 components as the center groove isolates both sides of a given row. This isolation restricts electrical connection between both sides. <\/p>\n\n\n\n How to wire a Breadboard<\/strong><\/p>\n\n\n\n Note how the holes colored in orange are connected together. These sets of connecting holes can be called a node, where it\u2019s possible to interconnect the node from bus strips to terminal strips with jumper wires<\/a>!<\/p>\n\n\n\n The metal clips are what goes underneath the bus and terminal strips and can be seen when a breadboard is either taken apart or has a transparent outer layer. The function of these metal clips is to grab onto an electronic component when it\u2019s plugged into the pinhole. They are spaced 2.54 mm apart.<\/p>\n\n\n\n *Which electronic component can you use?<\/strong><\/p>\n\n\n\n Now that we’ve talked about the breadboard pin functions and what goes underneath it. It is time to explain the labeling on it. <\/p>\n\n\n\n You may have spotted the numbering, letters, and signage written on a breadboard. These are written to help you locate the individual hole in the breadboard, similarly to how finding a cell in an Excel spreadsheet works. <\/p>\n\n\n\n The example as seen above: Hole C12 = Column C, Row 12<\/p>\n\n\n\n What do the “+” and “-” signs mean?<\/strong><\/p>\n\n\n\n Numbering and letters aside, the positive and negative signs on both sides of the breadboard are power rails, used to power your circuit by connecting the battery pack or external power supply. <\/p>\n\n\n\n There’s no physical difference between positive and negative buses, where labeling is merely for reference and better organization of circuits.<\/p>\n\n\n\n Power Rail Connection<\/strong><\/p>\n\n\n\n However, as power rails on either side are not connected, you\u2019ll need to connect both sides with jumper wires to establish the same power source on both sides.<\/p>\n\n\n\n Ensure that you connect the positive and negative ends respectively to the right end (positive to positive and negative to negative).<\/p>\n\n\n\n The center groove, also commonly known as the Dual In-line Package (DIP) support, is a groove that runs down the center through the middle of the terminal strips, hence its name. It allows integrated circuits (ICs) to fit onto the breadboard and DIP to be connected in a way that straddles that line. <\/p>\n\n\n\n The above components of a breadboard are commonly seen, however, there are other features unique to breadboards, such as the above-mentioned Grove – Base Shield V2.0<\/a>.<\/p>\n\n\n\n Features:<\/strong><\/p>\n\n\n\n When it comes to powering a breadboard, there are plenty of ways to do so. I\u2019ll be recommending the most common ones seen below:<\/p>\n\n\n\n If you\u2019re an avid Arduino user, this method would be the simplest for you! Since the Arduino already gets its power from a computer or external power supply, you can simply power a breadboard by \u201cborrowing\u201d its power supply.<\/p>\n\n\n\n Here’s how to power your breadboard through Arduino:<\/strong><\/p>\n\n\n\n Connect the Arduino GND pin with female headers to the breadboard power rails<\/p>\n\n\n\n The second way you can power a breadboard is through a battery, a step-by-step tutorial on how to connect an LED on a breadboard using batteries will be shown later! <\/p>\n\n\n\n Similarly to other electronic components, you can power the breadboard directly through our power supply adapter. This 5V & 3.3V breadboard power supply includes a micro-USB port and power jack port, allowing the taking of direct power from a DC wall wart and outputting it in 5V and 3.3V regulated voltage!<\/p>\n\n\n\n Note: Other power supply methods exist, such as binding posts and benchtops. However, these methods are only applicable to certain breadboards and are less commonly used compared to the above 3 ways.<\/p>\n\n\n\n Quick breadboard powering tip!<\/strong><\/p>\n\n\n\n A general breadboard can handle a power of 5V at 1A, but it’s recommended to keep it below 0.5A\/500mA for safety purposes<\/p>\n\n\n\n Earlier, we understood the principle of breadboard but now comes to the part where you start building your first breadboard circuit! I\u2019ve provided a tutorial for both beginners and Arduino users to try!<\/p>\n\n\n\n Before we move on to an actual breadboard circuit tutorial with LED, here are 3 crucial steps you need to first know in establishing a breadboard circuit connection with resistors and power supply<\/p>\n\n\n\n Step 1:<\/strong> Connect one of the power supply terminals to a hole of any section on the breadboard<\/p>\n\n\n\n Step 2:<\/strong> Connect one terminal of a resistor to the hole of that section such that both devices are connected to each other<\/p>\n\n\n\n Step 3:<\/strong> Take another resistor and connect it to the hole of another section. Connect the second power supply terminal to that same hole<\/p>\n\n\n\n Now that you’ve understood how to establish a simple breadboard circuit connection, here’s a tutorial from Starting Electronics<\/a> to help you get started with building a breadboard circuit with LEDs!<\/p>\n\n\n\n Here’s what you need:<\/p>\n\n\n\n Step 1<\/strong>: Insert the LED into the breadboard<\/p>\n\n\n\n Plug the LED’s longer lead (anode) into the breadboard’s top rail and the shorter lead (cathode) into a hole in the main part of the breadboard.<\/p>\n\n\n\n Step 2<\/strong>: Insert the Resistor into the breadboard<\/p>\n\n\n\n Plug one of the leads of the resistor into a hole directly below the cathode lead of the LED and the other lead into a hole below the middle channel of the breadboard. This connects the LED cathode to one of the resistor leads. It does not matter which way the resistor is plugged into the breadboard.<\/p>\n\n\n\n Step 3<\/strong>: Insert the wire link into the breadboard<\/p>\n\n\n\n Insert a wire connector into a hole directly below the resistor lead and into the bottom rail of the breadboard<\/p>\n\n\n\n Step 4<\/strong>: Insert the battery into the breadboard<\/p>\n\n\n\n Plug the battery’s red wire (+) into the top rail and the black wire (-) into the bottom rail.<\/p>\n\n\n\n An Electrical circuit should now be formed, with the LED lighting up.<\/strong><\/p>\n\n\n\n Note: You can completely rearrange the layout of the circuit but following the breadboard diagram exactly is the easiest way to get started with building a breadboard circuit. <\/p>\n\n\n\n Bonus! Want to build a breadboard circuit without buying a physical product?<\/strong><\/p>\n\n\n\n If you wish to learn and build your own circuits without buying an actual breadboard, you can use Fritzing<\/a>, a free software program allowing you to build a breadboard circuit without physically getting one! <\/p>\n\n\n\n Besides, if you are looking to learn electronics, design & build circuits, go to Electronics tutorials<\/strong><\/a> for self-learning. They have compiled a list of the best resources that can help with your learning.<\/p>\n\n\n\n For this Arduino breadboard tutorial, we\u2019ll be sensing water level using the XIAO SAMD21, the smallest Arduino board in the Seeeduino Family<\/a> that\u2019s packed with SAMD21G18 and applicable for breadboard usage!<\/p>\n\n\n\n Step 1:<\/strong> Insert the XIAO SAMD21 into the breadboard, and reserve the wiring positions on both sides. The row of each pin on the left and right is connected <\/p>\n\n\n\n Step 2: <\/strong>Connect the 4-pin Male Jumper to Grove 4-pin Conversion Cable with Grove – Water Lever Sensor<\/p>\n\n\n\n Based on the pinout above, connect the jumper side as follows:<\/p>\n\n\n\n The Grove side of the cable is then connected to the Grove – Water Level Sensor<\/strong>.<\/p>\n\n\n\nTypes of Breadboards?<\/strong><\/h2>\n\n\n\n
