How the Circuit Works• Operates with TL082• Has two operational amplifiers• Left and right LED's are connected in
series • 1K trimmer to adjust the
voltage input to the LM3914

CONCLUSION
![Page 24: Defense](https://reader035.fdocuments.net/reader035/viewer/2022062613/5447a013b1af9f4a228b46ed/html5/thumbnails/24.jpg)
Limitations• Very few literature• Too straightforward– does not hold much promise as bug
detectors, metal sensors, or alarms
• The light emitted coversvery short distance (5-10m)
![Page 25: Defense](https://reader035.fdocuments.net/reader035/viewer/2022062613/5447a013b1af9f4a228b46ed/html5/thumbnails/25.jpg)
Limitations• effectivity decreases during the
morning• function leans towards aesthetics
rather than practicality
![Page 26: Defense](https://reader035.fdocuments.net/reader035/viewer/2022062613/5447a013b1af9f4a228b46ed/html5/thumbnails/26.jpg)
Recommendation• replace the ordinary LED with super
bright LED– to stand independently of the light
emitted by the sun
• increase the quantity of the LED
![Page 27: Defense](https://reader035.fdocuments.net/reader035/viewer/2022062613/5447a013b1af9f4a228b46ed/html5/thumbnails/27.jpg)
Recommendation• connect to a remote control– Enable access from both inside and outside
the vehicle without physical contact– adjust the speed of the LED
• formulate better protocolsto improve the circuit’s mechanism
• eventually discover more feasibleand practical purposes
