An integral, long-lifetime, laser diode-triggered 50 kV/10 kA gas switch based on a kind of fast named light-initiated multigate switch (LIMS), is described in this article. The principle of this ...

LazerTripWire Overview This project is a laser trip wire system that uses a Laser Diode, Light Dependent Resistors (LDRs), and Servo Motors. The system can be used for security purposes, triggering ...

Laser Diode Positive Pin (+) → Connect to 5V pin on the Arduino. Laser Diode Negative Pin (-) → Connect to GND on the Arduino. LDR (Light-Dependent Resistor) Connection: LDR Pin 1 → Connect to 5V on ...

Last Updated: 7/27/18 Teaching Standard: In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates (blasts) the ...
