For infrared emitter Arduino Library file
Pin Spacing: 2
Two of the input value of potentiometer are respectively to show the user offset in the X and Y axis
It is easy to use as a led is on when the liquid level reached and voltage is detected from sensor output
Line Tracker (Finder) Sensor 3 Axis Digital For infrared emitter Arduino LibraryThis is high performance line finder that is designed for line following robotic. It consists two parts an IR emitting LED and an IR sensitive phototransistor. It can output digital signal to a microcontroller so the robot can reliably follow a black line on a white background, or vice versa. The sensor is Arduino compatible. Feature Small size. 5V DC power supply. Indicator LED. Digital output. Distance: up to 3 cm Pin Definition GND: Ground DO:
