Dim LEDs from anywhere in the world
You have probably already seen those LED strips that you can control remotely. We are going to do the same in this recipe (with three LEDs of different colors), but in this project you'll be able to control those LEDs from anywhere in the world.
Getting ready
For this recipe, you are going to need three LEDs of different colors (I used a blue one, a red one, and a green one). For each of those LEDs, you will also need a 330 Ohm resistor.
To assemble the project, first place all the LEDs on the breadboard, with each one of them connected in series with a resistor, the longest pin of each LED connected to the resistors. Then, connect all the free pins of the LEDs to the GND pin of the Arduino board. Finally, connect ...
