Once I started cutting the top off, it seemed quite easy to cut into the pumpkin. However, when I discovered how much there was inside, I felt slightly disgusted. It did not smell like lovely pumpkin soup, but of some unripe vegetable. It was not very difficult to get all the content out, but the space inside the pumpkin was surprisingly small. At that point I started wondering whether there will be enough space for the arduino board as well as the sensors and so on. Moreover, I realized, it will definitely be a challenge to keep all the cables and wires dry.
Then I cut out the eyes in form of stars. Though that may seem strange for a Halloween pumpkin, I do not intend to make the pumpkin look scary. It is going to be a friendly pumpkin, maybe even a pumpkin girl. Behind the holes of the eyes, I put colored plastic stars. Their surface will hopefully be large enough to show the LED's light effectively from within the pumpkin. The next step is the mouth. I let her show her tongue considering that there will need to be space for the Ping sensor, so nothing should get into its way and the real distance in front of the pumpkin can be measured.
