My first experiment with the Arduino board is a moving panda toy. The panda has 2 inputs and 2 outputs. The toy is made of paper and is placed on the servo. The eyes of the panda are made of LED lights. The panda moves independently when connected to the code. The LED lights are activated by clicking on the button attached to the Arduino board and the panda blinks its eyes.
The panda toy is connected to the Arduino board here:
My other project with the Arduino board is an LED Square Pixel Matrix that interacts with music and presents the music beats in a graphical lighted form. This matrix helps the user see the difference in tempo and beats per minute of the various music genres selected. It reflects the beats as well as the volume of the music.
