flash-cat

A flashlight that can copy a color. Like a copycat, but a flashlight -- a flash-cat.

Programmed with an Arduino.

These are the parts I used, though it would be easy to change out the board and LED ring:

• ItsyBitsy M0
• Flora Color Sensor
• An old flashlight and some batteries.
• NeoPixel Jewel

Pictures and things coming soon.

Setup

Software

Quick Overview

Download flashcat.io and load it into your Arduino IDE. Use the Arduino's Library Manager to install these Adafruit libraries as necessary:

• Adafruit_TCS34725
• Adafruit_NeoPixel
• Adafruit_DotStar

From Arduino's BoardManager, select Adafruit ItsyBitsy M0 in the list of Adafruit SAMD Boards. Select the appropriate programming port, and upload.
