P&ID shows process equipment and instrumentation interconnections. Also known as mechanical flow diagram (MFD). Superordinate to process flow diagram (PFD) showing general plant processes
Stepper motors are brushless DC motors with precise position control. NEMA17 motor has 200 steps per revolution with 1.8 degrees per step resolution. Drivers enable precise control through H-bridges and microstepping
Unity's new Input System is now official and offers advanced features. System replaces old Input Manager with more customization options. Installation requires Unity 2019.1 or newer and Package Manager
Servomotor is a rotary or linear actuator for precise position control. Consists of motor, position sensor, and controller for closed-loop control. Uses position feedback to control motion and final position
Arduino Library includes boards like UNO, Mega, Mini, Pro Mini, and Nano. Genuino Library features boards similar to Arduino's. GPS Library simulates skm53 GPS module for location detection. GSM Library simulates SIM900D GSM module for SMS communication. XBee Library enables wireless communication using RF protocol
NPN and PNP outputs provide binary (ON/OFF) information in industrial sensors. Standard wiring: brown (power), blue (ground), black (signal). PNP outputs change signal voltage when sensor activates. NPN outputs require pull-up resistance (4.7kΩ) for signal detection
