In this holiday season, almost everyone has done their Christmas tree in your home, small or large. In this post, we will see how to create a Christmas tree with a few €, using Arduino. Through this microcontroller will be able to choose from several different profiles, which allow you to sing and illuminate our "tree".
What do you need?
Infrared remote control
Box Pandore / Panettone
Felt-tip pens or watercolors
Step 1: Explanation of the project
Explanation of the project
At the base of the project, there are several components, each with a specific goal:
The LEDs are simply diodes that light up when there is a current step, typically a few tens of mA. The potential drop between the anode and cathode is typically a few volts
This device allows you to play the Arduino through a current flow in the device. Through the calculation of the period of a particular note, you can play it with your device. Here's the full list:
