Take an optical mouse (defected) and disassemble mouse circuitry.2. Cut all the wires of optical mouse circuit except data, Vcc, GND wires.3. Disconnect the optical mouse circuitry LED and place a buzzer with +ve pole of buzzer to the LED cathode terminal.4. Connect the -ve pole of buzzer to the LED anode terminal.5. There are 4 wires in circuit. D+, D-, V, G.6. Connect V wire of circuit to the +ve of 9v battery.7. Connect G wire of circuit to the -ve of 9v battery.8. Made the whole arrangement and place on the cardboard.9. Take a laser light and connect with a mobile charger.10. Put the laser light in front of optical mouse sensor. There is a hole on the sensor and use mirror for multiple reflection.11. Check when you place a hand and disturb the laser from sensor hole and make sure that the buzzer beeps.Now, you have all set.Your laser security alarm is ready..secure your home and office or any place with this defected mouse.Thanks....Do subscribe my YouTube channel &#34;Electronics is Fun.&#34;<figure><img src=https://projects.arduinocontent.cc/0d68cca3-8090-49c6-83a2-2b805642340a.png /><figcaption> </figcaption></figure>This is the optical mouse sensor.<figure><img src=https://projects.arduinocontent.cc/a97c12d7-2966-482f-8d91-21daf7a0b2c3.png /><figcaption> </figcaption></figure>Connect the 2 wires as shown to connect buzzer.<figure><img src=https://projects.arduinocontent.cc/ca7e645f-f079-434c-a655-69c0471e5d54.png /><figcaption> </figcaption></figure>This is the figure to connect buzzer.<figure><img src=https://projects.arduinocontent.cc/5a12412e-4ed3-4d2b-8fe4-7d76b5160c98.png /><figcaption> </figcaption></figure>Connect 9v battery as shown.<figure><img src=https://projects.arduinocontent.cc/933aa5bf-73ba-49c4-aa93-39398d2f733f.png /><figcaption> </figcaption></figure>Made the whole arrangement on a cardboard.<figure><img src=https://projects.arduinocontent.cc/8b1b5706-f0f1-4976-ac14-0ebd7b6f4be9.png /><figcaption> </figcaption></figure>After placing all the components it will look like this.Thanks...
