What happens if you try to wire 10 LEDs, with only wires and the Arduino board?
Just using wires is gonna turn your project into a wire spaghetti! 🍝
We can use a breadboard to:
1) Hold your components
2) Connect and disconnect them and try different circuits.
3) Whatever other benefits you can think of!
We will learn:
How Electric Current Flows on the breadboard ⚡
Lighting up 1 to 3 Blue or as many LEDs with wires and the breadboard.
⚡How to power your LEDs and components on the breadboard
What do we need for this Tutorial?
1 Arduino Uno board and USB cable
3 M-M Jumper wires (20 cm)
5 Blue 5mm LEDs
Try this #1: Place the LED correctly and light it up
Try this #1: Place the LED correctly and light it up
Try these 6 challenges: Set the wiring show below, and place the Blue LED on the breadboard correctly and make it light up.
Even if you don't know the answer, just try to keep guessing!
While doing, think how the breadboard works
Hint 1 : Use 3.3V, not 5V or you will likely burn your Blue LED
Hint 2 : Remember, check where you need to put the short leg (negative terminal)

What is going on on the Breadboard? 🍞
What is going on on the Breadboard? 🍞
The surface of the breadboard is plastic. So why does the LED light up? 💡
If you can guess, there is probably a conductor under it. Which is metal!
Here is a breadboard where the double-sided tape has loosened and fell off.
Notice how the metal plates are arranged, that allow current on your components to flow.
*Please don't pry yours, its hard to put back!
Reflect: Can you tell yourself:
When will the component work or not work on a breadboard?
Can you see how the current is flowing from Positive (+) to Negative (-) from Arduino pins?
If you think you do, try to see if you can answer below.

C1: No it won't 🙅♀️
C2: No it won't 🙅♂️
Try correcting them by trying it out on the breadboard!
And with that, what is the keypoint that you learned?
Hope this helped you with breadboard.
(Fun thought: why is it called breadboard? 🍞)
Good luck making! 👍
