A Maker by the name of Tamberg has designed an Augmented Water device that helps save water by turning red and alerting the user when a single liter has been dispensed.
Additional components include:
- LiPo battery
- LiPo charger
- Jumper wires
- M-M Tube fitting the sensor
- Plastic test tube
- Zip ties
Tamberg kicks off the project by preparing and testing the neopixel LEDS, configuring the flow sensor and testing a specially coded Arduino sketch. He then creates a tap adapter and fits the various pieces together.
“Attach the two (green) tubes to the flow sensor, with the adapter at the top. Use zip ties to attach the Neopixel strip to the assembly. Make sure the wires are at the upper end (with the adapter),” Tamberg writes in a recent Instructables post.
“Use an additional zip tie to hold the flow sensor wire, then mount the Arduino on top of all this. The Arduino’s upper side should point inwards, [so] make sure the USB port remains accessible for updates.”
