Hello Creator, I loved your video quality and explanation. I have some doubts if you can answer, please. Why is the A0 connected at the junction of LDR and the resistor? Also, If I want to display the resistance of the LDR on the serial monitor, how do we do it? Looking forward to your reply.
You can't. The way the LDR works is via the chemicals in the sensor. However you can create an offset or make your code work with another sensor value. Keep in mind that over time these sensors wear so you might need to adjust the code anyway (or use a potentiometer to set the correct threshold)
it works
Great! 😃

Looking forward to your reply.
Thanks! The connection is called a "pulldown resistor". I'll explain this in ruclips.net/video/5aR0cHKc-JA/видео.html 😃
@@BasonTech Thanks man!
Amazing video is it possible to show light intensity value on a LCD?
Sure! Just combine this tutorial with my tutorial about the LCD screen and you should be able figure it out! 😃
Can I use a attiny for this?
Yeah that should probably work 😃
How can I calibrate LDR?
You can't. The way the LDR works is via the chemicals in the sensor. However you can create an offset or make your code work with another sensor value. Keep in mind that over time these sensors wear so you might need to adjust the code anyway (or use a potentiometer to set the correct threshold)
