I bought a photoresistor-based module. I tried to improve it by adding a decoupling capacitor to the LM393, adding a transistor to have a true 0. I also added an input and an output for the load. Thus, the load having its own power supply, it will not be bothered by that of the module. I am a beginner in electronics, sometimes I have good ideas, but the realization is more difficult. Could you tell me what you think of this circuit? Thank you in advance.
