October Makers Meeting!

On Sunday October 6th we had our monthly meeting. Brad showed us his Arduino test rig and animatronic pumpkin.

The test rig had an assortment of fun components to play with.

  • Potentiometer
  • 7-Segment LCD
  • 16 x 2 Character LCD Screen
  • 128×32 OLED Screen (Link)
  • NeoPixel Sticks (Link)

The Arduino reads the position of the potentiometer and based on that reading, it will run a particular program. This allowed Brad to switch quickly between programs rather than re-programming the Arduino each time. This looks like a great way to have a lot of fun learning Arduino connectivity and programming.

Checking out the cool stuff!

The Arduino-controlled animatronic pumpkin has a lot of motion in a small package. The jaw, top, eyes, nose, and eyebrows all move. It also has speakers and a wav-player for sound. There are several R/C servos to provide the motion, all connected to linkages made from copper wire and tubing. The tubing acted as bushings and the wire acted as both structure and shafts at the pivot points. Check out the image below to see all the components that went inside.
