Circuit Opto-Thermo Control Relay Switch with IC 741 This be Electronic switch circuit is onely. Which work with the light and the temperature. I begs for to call that Opto-Thermo Control Relay Switch with IC 741. By have work various instructions very much. And have onely observations be I uses IC 741 then can insist [...]

Circuit Light Change Detector by IC CA3130 This the Secretariat of the Swith light high-quality circuit. By prominent its point is when the light changes the system will order to give Relay work immediately. Detect the change in the light that get from the circuit is will that. We use IC op-amp number CA3130 work [...]

This is same circuit as above with the addition of a photo resistor to trigger the flip flop instead of a push button. The bias resistor in series with photo resistor was chosen so that sufficient voltage is present at the base of the 2N3904 to supply current to the circuit in ambient lighting conditions. [...]
