digital logic - Automatic switch using LDR


enter image description here


I've implemented above circuit and it was successful. The given circuit needs 12VDC to run properly.


I want to run this circuit on 5-6VDC or 9VDC whichever is possible. I know I have to change resistors but not confirmed which to use.


Also if I use 9V battery only to activate 6V relay for 8hrs daily, for how many days will that battery work?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
