Light Sensitive Staircase Switch with Triac
Operation of the third circuit is much similar except that it has photo sensitivity. The circuit is shown in Schematic
When there is no sufficient light/the reset pin is held low by R14 (4.7K resistor) and the circuit works as it is described in the earlier paragraph. But if there is sufficient light, resistance of LDR [...]
