But it is really important to use the correct resistor value in the circuit to limit the current. The circuit will be something like shown above. The importance of anode and cathode pins in LED is that, LED will glow only is you provide +ve power supply to Anode pin and – ve power supply to Cathode Pin. But wait, you cannot straight away supply the LED with power supply because there are chances that more current will pass through LED and this will lead to damage the LED, to avoid this situation, it is strongly recommended to use the resistor along with LED. But most of the times you have to trim the legs of LED when you use these LED in any circuit thus making the anode pins and cathode pins indistinguishable in terms of Leg size. If you notice the above image you will see the legs of LED mentioned with Anode and cathode and to understand how to distinguish between anode and cathode pins, we provided hints in the image, its nothing but one cut mark(Means the LED is not completely round from the bottom side) which indicates that the leg underneath it is cathode(-ve) pin and if we seen the size of the legs, the anode(+ve) pin is little longer. We are going to start with LED circuit, which is common to all the devices, we are going to build a circuit for Power LED Indication, i.e whenever there is power in the circuit, this led will let us know about it. Hope things are clear to this point and you understood the breadboard well, now we will move further and see how to start building basic circuits on this breadboard. The image shown above is of Half sized breadboard, thus don’t be confused comparing it with previous images. To make things further clear, we have added the tear down image of the breadboard, refer the next diagram to get better idea of inside connections. The center holes are column connected as shown in the picture and there is a gap in between the same columns, allowing us to fit in IC to the gap. Refer the Vcc and Gnd Lines in the image above, you can see these two lines are running round the borders, thus allowing us to use these lines for power supply distribution, but there is a discontinuity in Vcc and Gnd tracks as shown above(mentioned “Not Connected”), which you need to connect with jumpers to distribute the power. If you refer the description in the image above you can see that the how tracks are connected inside the breadboard. You can use breadboard to test and figure out the working of Integrated circuits (ICs). In case one breadboard can’t accommodate your circuit, you can snap in multiple breadboards together to make a big breadboard base. These metal strips are springy so that when you poke a wire or component into the hole, the clips grab onto it.īreadboards are used for both the simplest circuit as well as very complex circuits. You can’t see what’s going inside the breadboard, but inside its nothing but many strips of metal that connect the rows and columns together. They are inexpensive and reusable and they are easily available in any electronics store.īreadboard is nothing but a plastic base with lots of holes in it, where you can fit in your components and wires to build your circuit. They allow you to make quick circuits, test out ideas and allow prototyping before making a permanent Printed Circuit Board. Breadboards are preferred platform to start building circuits because it don’t need any soldering, thus giving you the flexibility to try, test and modify your circuit at any point of time. Breadboards are one of the basic element when you start learning how to build circuits. *Base Rate + $1.Heard of breadboard?
