Physical Automation (Pneumatics)

Cyclic Hardware Integration

Although it has no cloud source code because it is strictly physical, I have experience and foundation in the development of electropneumatic automation and pure mechanical systems.

My expertise encompasses orchestrating limit switches, pneumatic actuators (cylinders), and logical controls driven by air or electricity. Essentially, I design loops where the physical action of a cylinder presses a sensor, which releases air flow (or electrical current), switching the main valve and feeding back a continuous cycle without human intervention.
