Hello Experts! Here is my simple clap switch schematic. First let me know is it correct or not? I have used 555 timer in monostable mode here this means LED will remain on for the particular period of time defined by R3 and C1 i.e. T=1.1(R1)(C1). Let I use red LED here. So I think 1.7V is its voltage drop and 5mA of current to turn it on. I have used 6VCC biasing. I want to know 2 things. 1)Is this circuit is correct, means any component is less or you think it should be here which is not? 2)What should be the values of components here? and how will I know which transistor is to be used here? Thanks in advance.
