Description: "Fidget" boards: one with traditional single-colour LEDs and the other with multi-colour Neopixel RGB LEDs. The single-colour LEDs version will fit in a small Hammond project box.
Features: - Moderate current draw with both traditional 3mm LEDs and neopixel RGB LEDs - LiPo battery can run either board when you're away from your PC's USB port - 1000uF surge cap for RGB Neopixel LEDs and current limiting resistors for power and data signals - 3v3/5v level shifter for data signal (RGB board) - Amplified buzzer speaker
Details: - Either 1 matrix of 9 regular LEDs (LED board) or two matrices of 9 Neopixel RGB LEDs (RGB board) are arranged in a 3x3 matrix. In the lower half of the left panel, the breadboard prototype is only showing 4 RGB LEDs - Pressing the GO button causes the matrix to progress through predefined display patterns - RGB Neopixels can have multiple uses including that of rolled dice - On the RGB board, a jumper allows you to code for both RGB matrices independently or combined into a single large matrix - Utilizes a powerful Adafruit QT-PY SAMD21 or QT-PY RP2040 microcontroller - Many SMT discrete components were used where possible - On-board 500mA LiPoly battery charger - Mounting holes are provided if you wish to use a 3D-printed case or Hammond project box
Software: - Libraries and Neopixel learning document - Optional Fast LED library
Software for LED Board: - Here are some blink routines I have written for the QT-PY LED board: QT-PY_3x3_LED_Array.ino. The code is in a state of flux as I update it regularly. You'll notice that each of the routine sets has its own folder within the Arduino IDE: Bands.ino, Beeps.ino, Blinks.ino, Wipes.ino.
Software for RGB Neopixel LED Board: - Demo and games have yet to be designed - Here are some RGB Neopixel LED test patterns I've written
