IC555 clap switch with timer mini project circuit

This is a special application of IC555 clap switch with timer mini project. It uses a condenser mic to pickup the clap like sharp sound and trigger the IC 555 designed as monostable multivibrator, as shown in the following circuit. Working of the circuit The circuit uses one condenser mic to receive the clapping sound and Read More

IC 555 soft touch switch door lock mini project

This is a very interesting IC 555 soft touch switch door lock mini project. It is very easy to construct and useful for your school or college level mini project submission. The actual size PCB layout of the project is also given here, so that you will be able to construct it within an hour if Read More

Animated working of bridge rectifier circuit

Why am I publishing this animated working of bridge rectifier circuit? Because in my long teaching experience, I have noticed that sometimes, the 11-12th standard students get confused with the working of bridge rectifier and cannot properly explain it. This same case occurs for HWR & FWR circuits as well. So I have created the animations of all these three Read More

Why I am publishing this animated working of full wave rectifier circuit? Because in my long teaching experience, I have noticed that sometimes, the 11-12th standard students get confused with its working and cannot properly explain it. This same case occurs for HWR and BR, as well, which are also explained. So just watch the video given Read More

Why I am publishing this animated working of half wave rectifier circuit? Because in my long teaching experience, I have noticed that sometimes, the 11-12th standard students get confused with its working and cannot properly explain it. This same case occurs for FWR and BR, as well, which are also explained. So just watch the Read More

IC 555 Infrared Burglar Alarm circuit

This is another circuit of IC 555 infrared burglar alarm project. It is very simple to construct and submit it as a mini project for your school and college level project submission. The basic idea of the circuit is almost same used in the previous circuit of IC 555 simple burglar alarm, only the wire loop Read More

IC 555 Simple Burglar Alarm Circuit

This is another circuit of IC 555 simple burglar alarm mini project. It has been fully tested in our lab and its PCB layout is also given below. The circuit uses the simple trick that whenever, pin-4 i.e. the RESET pin of IC 555 is grounded, all its functions stop. But when it is raised to Read More

IC555 head or tail toss project circuit

IC 555 Head or Tail Project

This is a very interesting circuit of IC 555 Head or Tail Project. It uses a simple trick that if we break the charging path of the timing capacitor in AMV circuit using IC 555, then the output condition of the circuit remains locked in a particular state. Working First note that the circuit uses PUSH Read More

ic555 fuse indicator cum pilot lamp circuit

This is the circuit of IC555 Fuse indicator cum pilot lamp. You can use this circuit for mini project application in your school or college. The circuit is very simple to construct and uses simple trick that whenever, the external capacitor C1 is fully charged the output of the IC remains LOW, but when the fuse Read More
