Stack the PCBs and plug in the connector just made. In the images above, there are 4 boards stacked on an Arduino Uno. Each board provides 8 solenoid valve connectors, and the current design supports ...

Through testing the orifice inside the solenoid valve was relaxed from 2.5mm to 3.5mm to achieve an ideal cold and warm engine idle speed of 850rpm. Further work could involve replicating the Arduino ...

[TVMiller] hacked together a feature-packed controller for his existing shower valves. An Arduino MKR1000 reads the water temperature and controls the servos that allow him to start the shower ...
