Arduino For Kids: Tripwire Alarm
In this video we use an Arduino Nano, a Piezo speaker, an LED, a resistor, an LDR and a LASER diode to create a fun, cool, LASER Tripwire Alarm. The diode LASER shines a very narrow beam. The LDR receives the beam and the Arduino Nano monitors the LDR for any change. If the beam is broken, the Arduino goes into alarm mode and sounds an audible alarm and lights a red LED to warn of intrusion.
