Just started electronics ? And you don’t know any engineering behind your projects and you are afraid of failure ? Then, this article can help you get started in electronics. Usually, success in initial projects plays important role in electronics amateurs and engineering students’ career. Many students quit electronics because they fail in their first,…
Here’s one of the easiest, simplest and the most popular FM transmitter for amateurs and electronics beginners. With this DIY kit, you can transmit your voice or audio over an ordinary FM radio within the FM broadcast band. It is a DIY kit designed by Sagar Sapkota. You can buy this kit at BuildCircuit Store….
There are hundreds of electronics projects published on buildcircuit.com. This time we have selected few projects that should be easier for beginners to start with. Complex and difficult projects just frustrate the beginners. The best thing about the listed projects is that all come with good assembly images and most of the projects can be…

We all know that troubleshooting is a process of identifying and solving problems that cause a circuit to malfunction. This article is about troubleshooting basic and amateur electronic projects, not about sophisticated devices . With the exception of minor problems,troubleshooting sophisticated systems at the circuit level, like computer, VCR, mobile phones, etc. requires special skills,…
Description: This circuit can be used for testing your TV, DVD, VCD, etc. remote control. This is the fundamental module for making infrared based object counter. This project has been derived from “Remote tester project” .
Description: Astable mode of 555 timer is used to generate pulses at regular interval. READ ABOUT ASTABLE MODE. The following schematic has been taken from buildcircuit.com. The following circuit can work as a music generator, Infrared transmitter and LED blinker depending upon the values of R1, R2 and C1.
Here’s a simple light activated police siren using light dependent resistor and NE555 timer. Before you make this project, I would recommend you to make the following projects. a. Light sensor and dark sensor I strongly recommend you to make a dark sensor and light sensor using LDR and understand clearly how it works. b….
An electret is a permanently charged dielectric. It is made by heating a ceramic material, placing it in a magnetic field then allowing it to cool while still in the magnetic field. It is the electrostatic equivalent of a permanent magnet. In the electret microphone a slice of this material is used as a part…
This is a simple RC circuit using thyristor. You might have done similar projects using transistors. Let me provide you some of my previous RC projects: a. Basic RC project You can make several projects with this module, for example, Remote tester, object counter, etc.
For the circuit to work as light operated musical bell, we need to connect the SW1- switch to N/C terminal of relay. LDR has to be kept in a dark case.
An automatic dark sensor can be made using a PNP transistor(BC557).
