Hydraulic solenoid valve Forward/Neutral/Reverse control for auto-reverse, log splitter.
Simple hardware circuit to control common hydraulic solenoid valve.
Using Arduino / 43oh to automatically reverse the movement of a hydraulic actuator if pressure switch closes. Pressure switch is adjusted to close if there is excessive pressure in the system indicating end of cylinder stroke or mechanical jam. Also included are forward/reverse selector switch for normal operation. PCB only, no schematic, no breadboard sketch written for Texas Instruments MSP430 Launchpad.
