  • Dark/Light Detector using 555 Timer & LDR -

    2020-5-13 · The Circuit Diagram of Dark/Light Detector using 555 Timer & LDR is given below: This is a simple circuit that can be assembled in breadboard or zero PCB Board. The sensitivity of the circuit depends upon the 4.7K resistors. The resistor with slightly lower value can make the circuit more sensitive to particular light level.

    2015-8-5 · It is much easier, at least for me, than using the 555 as a schmitt trigger, where the hysteresis is so large (1/3 Vcc), unless a control voltage is applied to pin 5. For instance, if 2V is applied to pin 5, the hysteresis will only need to go from 1v to 2V (which is actually 1/2 Vcontrol to Vcontrol). Still, this complicates the setup.
