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…

The M348X series IC is a mask-ROM-programmed multi melody generator , implemented by CMOS technology.It is designed to play the melody according to the previously programmed information and is capable of generating 16 songs with 3 instrument effects : piano, organ and mandolin. The device also includes a pre-amplifier which provides a simple interface to the driver circuit. The M3481…
Description: This wireless transmitter and receiver pair operate at 315Mhz. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only transmitters, they will only work communicating data one-way, you would need two pairs (of different frequencies) to act as a transmitter/receiver pair….
This is a DIY touch delay LED kit parts. When the user touches the kit, all the LEDs turn on. It is a very basic learning kit for beginners and learners.
2 Channel Mini easy to use Relay shield for Arduino Nano consists of ULN2003 IC and 2 Mini 12V Relays with NO/NC contacts of 2A-24V Load Capacity. ULN2003 used as Relay coil driver. Relay can be controlled from D3 and D4 of Arduino Nano. Three-pin Header Connector CN1 and CN2 provided to connect the Load. Relay has normally open…

Note: Please remove the Wi-Fi module when you use USB connection. USB/Wireless Relay module…
This is yet another TDA2030A based audio amplifier DIY kit. The kit is retired and not so popular these days. An excellent tutorial on this kit is published on this website.
After getting several comments from young electronic students , I am rewriting this article to make the FM transmitter making process more clear. This tutorial is for making simplest FM transmitter using one transistor. You can make this project with less components and it is an easy and simple project for beginners. Before you proceed,…
In this tutorial, we will turn on and off the LEDs sequentially, such as Christmas tree lights.
With this project/application, you can make a light sensor dependent lamp. You can make a light sensor or dark sensor with this application. The light sensor of your Android smart phone senses ambient light present in your room and sends commands to Arduino board. Your Arduino program determines the behaviour of the LED, whether it…
In this tutorial, we will learn to connect and use the RTC (Real Time Clock) module to display date and time on the 16×2 LCD display. DS1307 is called the Maxim-Dallas module for Arduino with which it allows us to have a precise system clock.
This is a basic electronics learning kit based on NE555 and uA741. Check out the following images for assembly. You can see all the images on Flickr also. Other images of the kit:
