Hello folks, let me introduce you to the Pumpkin Pi. Simply put it is an I/O controller for the Raspberry Pi with twelve programmable outputs, but with a little hocus-pocus (or Python code to you and me) it becomes a digital decoration controller that offers two video outputs with audio, and lighting FX synced to video.
How it Works
It is basically a breakout board for the Pi that connects twelve of the Pi’s GPIO pins to NPN darlington pair transistors (in the form of three transistor arrays). When the relevant Pi output goes high, it switches the transistor to complete the circuit.
There are also two more GPIO pins that ‘link’ the two Pis together via pull-down resistors that act as triggers (more on this in the ‘Programming the Pi’ step later).
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
