LDRs or Light Dependent Resistors are very useful especially in light/dark sensor circuits. Normally the resistance of an LDR is very high, sometimes as high as 20000 ohms, but when they are illuminated with light resistance drops dramatically.

 

 

Specification:

  • Can be used to sense Light
  • Easy to use on Breadboard or Perf Board
  • Easy to use with Microcontrollers or even with normal Digital/Analog IC
  • Small, cheap and easily available
  • Dimension 5mm

প্রশ্নটি বোঝা গেল না। এলডিআর নিজেই তো একটি রেজিস্টর। Answered by A.R, 25-Sep-2016 10:13 AM

যদি কোনো ভারিয়েবল সার্কিট হয় তাহলে কাজের জন্য পাল্লা দিয়ে রেজিস্টর লাগাতে হবে এবং ohm বাড়াতে হবে। Answered by CyberPritom, 30-Apr-2017 00:46 AM

-এলডিআর দিয়ে কিভাবে পালস দেবেন, ভাই? এলডিআর তো কোনো পালস আউটপুট দেয় না। এলডিআর একটি রেজিস্টরের মতো। আপনি একে কোনো কম্প্যারেটরের ইনপুটে লাগিয়ে যদি পালস জেনারেট করে নেন তাহলে সম্ভব। Answered by A.R, 17-Sep-2017 11:19 AM
