My first attempt was using the 360 degree servo motor attached the Pikachu using normal thread. However I found out that the centre position of the servo motor keep changing, probably due to power shortage or something. Moreover the strength for servo motor could not help me to hold the weight of umbrella.
After that I moving on to in search for stronger motor where I came across stepper motor. I bought my motor from taobao.com which is cheaper then they sell in simlim. A motor shield also needed in order to make the stepper motor work, I bought a total of 2 kinds. One is a similar from Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit – v2.3 while another is Stepper motor drive SHIELD just in case one of them doesn’t work.
The Adafruit motor shield has many advantage as is it really easy to use and can drive up to 2 stepper motors. They also provide guidelines on how to set up the stepper motor! So first was to attached the motor shield on top of the arduino and connect to a DC motor to try if it works! [I am trying on a similar Motor shield not the actual Adafruit Shield.]
Next was to try out on the real stepper motor. This time DC Barrel Jack was use as the power source as the stepper motors needs more powers. It actually can work when I plug in the usual for arduino but the light was blinking unstably which means the powers is not enough. At first I was quite confuse with the wires connect to the motor shield but in the end everything manage to work!
