One of the advantage of an LED is that is does not use a lot of power and is a lot more efficient over a traditional lightbulb. If you look around, you probably see LEDs here and there: your phone, computer, battery charger, tv etc. Sometimes a translucent LED could for example lit in blue or red. the green lines mark how the holes are connected LED (Light Emitting Diode) a7 is not conencted with a8, because they are each in a seperate row. In the picture below a30 is connected with e30, but not with f30 because of the little gap in the center. Some breadboards have their holes labeled with letters and numbers.
This interruption ensures that the top and bottom halves are not connected to each other. The others are connected from top to bottom towards the center. The same goes for the minus holes (the blue line). This is useful because you don't need wires to create these connections.įor example, the breadboard in this photo connects all the top row holes marked with the plus sign together (marked with the red line). The holes are pre-connected in a special way. You can easily prick and remove all your components in the breadboard. This way you avoid having to solder and desolder components many times. You can use it for proof of concept circuits which can later be designed as a printed circuit board or soldered. What is a breadboard?Ī breadboard is being used for building temporary circuits. This button allows you to download the code, circuit diagram and other files relevant to this Arduino tutorial. For example, do you know why we have to put a resistor in front of an LED? No? Then read on quickly! 🤓 Course materialĪt the bottom of this page you'll find the course material button.
This might seem boring (it is a little bit 😉), but it forms the basis of all the other lessons we are going to do. Now it is time to start using a LED on a breadboard.

In the previous lesson, you blinked the built-in LED on theĪrduino.
