It often happens that we start filling up the kettle and forget about it. When we remember, the water is already falling down from the ceiling of our neighbor below. To prevent this from happening I created a system on an Arduino which has a water meter and a solenoid valve. With such a system you can connect up to two filters. I have a drinking water filter and a reverse osmosis filter. The system is able to count the remaining life of your filter and you will know exactly when you need to replace the filter. We also have 4 buttons. Kettle, Glass and Finger buttons refer to the drinking filter and the button Jug is for the reverse osmosis filter. With these buttons you can quickly choose desired amount of water. Each one of this presets can be adjusted in the menu. The water meter has a calibration function, storing data into non-volatile memory and mutable buzzer. It is also possible to set the volume of water to be filled for each button. <div> <img src="http://things.ruvim.info/ARCH/ruvim/Shema/Butoon.jpg" alt="Smart faucet on Arduino" title="Smart faucet on Arduino"> </div> By pressing the "Finger" and then pressing the "Encoder" we can rotate the encoder and set any amount of water we want in increments of 50 milliliters. If you like my projects please “like” them. This will help a lot for further development and new projects. <center><h2>Connection diagram</h2></center> <div> <img src="http://things.ruvim.info/ARCH/ruvim/Shema/Scheme12.jpg" alt="Smart faucet on Arduino" title="Smart faucet on Arduino"> </div> <h3>Links to materials:</h3> <ul> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_AEwLZs" target="_blank">Touch Buttons</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_AAPimA" target="_blank">Arduino pro mini 5V 16MHZ</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_AFvM0O" target="_blank">Programmer</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_AWz5Gm" target="_blank">Power Supply 5V 2.5A</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_ALKJxy" target="_blank">Counter</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_ADMKZ8" target="_blank">MOSFET</a></font></li> <li><font size="3"><a href="http://ali.pub/5iyhv8" target="_blank">Screen</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_A9DK7u" target="_blank">Solenoid valve</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_A1XpuW" target="_blank">Encoder</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_9h71JY" target="_blank">DC-DC step-up module</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_AlTdnY" target="_blank">Beeper</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_AMCjRu" target="_blank">Black hot melt</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_AnehEI" target="_blank">Wires</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_9GLYMA" target="_blank">Terminal kit XH2.54</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_A7g0NY" target="_blank">HER105 diodes</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_9uOVgE" target="_blank">Covers</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_9wTIHY" target="_blank">Fittings 1/4</a></font></li> </ul> <h3>Links to used tools:</h3> <ul> <li><font size="3"><a href="https://www.banggood.com/custlink/mGmEtgtyhA" target="_blank">TWO TREES TOTEM S 40W Laser - Promotion Code (BG2RUV), $259.99</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_AU64UI" target="_blank">Crimping pliers XH2.54 SM needed (SN01BM)</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_A7ai8e" target="_blank">Metal brush</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_APxwH0" target="_blank">Caliper</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_9HMnb0" target="_blank">Medical clamp</a></font></li> <li><font size="3"><a href="http://ali.pub/5j5czn" target="_blank">Layout board</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_AU2ukO" target="_blank">Glue gun</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_AEQSwi" target="_blank">Tweezers set</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_9xlbGK" target="_blank">Infrared thermometer</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_9zJshY" target="_blank">Side cutters </a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_9RgvNG" target="_blank">Heat shrink dryer</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_ANXBt8" target="_blank">Tightening tool for ties</a></font></li> <li><font size="3"><a href="https://s.click.aliexpress.com/e/_AftrwW " target="_blank">Bit with a magnet</a></font></li> </ul> <ul> <li><font size="3"><a href="http://my3d.art/?utm_source=p_rvk" target="_blank">Self-extinguishing plastic for the enclosure</a></font></li> </ul> <center><br> <div><a href="https://paypal.me/RuvimKUB"><img src="http://things.ruvim.info/img/pp.png" alt="Donate now" title="Donate now"></a> <a href="https://money.yandex.ru/to/410017640495006"><img src="http://things.ruvim.info/img/ya.png" alt="Donate now" title="Donate now"></a></div> Thank you for every review and donation,<br> It motivates and helps to implement new projects!
