Just delete the statements about the pots and this post fits in hee.
But if you conect an LDR in seris whith an batery and buzer wont it then waste a lot of power.Becos an LDR wond go fuly off anf full on ir will just change its resistance.So wen the buzzer is off the LDR is still pasig some curnet trough but too smal for the buzzer to run on and that is wasting the baterys.
