Hi. Have this Circuit When the lights reach LDR1, the resistance drops, and the T8 close, and the RESET on IC3 gets high( no Counts). when the dark hits LDR1 the resistance rise and the T8 opens up, and the RESET on IC3 gets low( Count) will this be right or have i missed something. ? If it is ok, then i could replace R16 with a VR. to adjust the time of darkness. The value of R17 = 5k? The value of R18 = 10k? R16 maybe 20k, LDR is 200k in the dark, 6k in light.
