V-LED This is the VCC pin of the LED. Connect this pin to the 5V pin of the Arduino with a 150Ω Current Limiting Resistor. LED-GND This is the Ground Pin of the LED. Connect this pin to the Ground pin ...

Arduino Flow Meter Sensor Code: In this project, we are going to build a flow meter sensor and pressure sensor using Arduino and displaying it on a LCD display. Flow sensor has a rotor and a Hall ...

Matching a sensor interface with a programmable logic converter or controller hardware that can accept only one type of input—npn or pnp—can be difficult. The last-stage modification circuit described ...
