An Arduino, a Ethernet Shield, Flow Meter, the Ethernet Bridge is just because no wired connection was close. Auto Dog Water Dish was bought online and a few fittings were needed to convert my 1 inch flow meter to and from standard hose connectors.
Pin 2 is used to receive pulses from Flow Meter. Note that the meter is not exactly the same as on AdaFruit, only the pulse factor is different. Adjust ratio in the code as needed. Ground and 5 volts pins are used to power the meter. The picture also shows a very short distance connection. Eventually I replaced that short wire with a longer wire relocating the electronics inside and out of the elements.
The Ethernet DHCP client connection, combined with Limor’s Flow Meter example and the ThingSpeak code makes this a very easy project. Only a few lines is original code. Tweeting is done using a react app within the ThingSpeak site. The project took only a couple hours.
My only problem with the project is that my dogs still prefer to drink from the pool.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
