This pocket-sized gadget helps build positive habits
Want to read more, remember to take your vitamins, or even take out the trash? With the “Dory” Arduino-based tracking device from YouTuber YellowRobot.XYZ, now you can!
Dory–which comes in both a circular and smaller square version–uses an NFC reader to sense tags attached near the object that needs work. When you complete a positive action, you simply tap the nearby tag and the small gadget will light up its corresponding LEDs via an Arduino Pro Mini.
If you’d like to know where you are on your habit count, this is displayed with a button in the middle, and can be reset by holding it down. Beside from tracking habits, Dory is a great reminder of what can be done with NFC tags!
