In this project, we are going to use a PIC microcontroller to remotely control few AC loads by just using an IR remote.

In this project, we are going to make a Voice Modulator Circuit, by using self-designed PCB. In this project, we have designed a PCB using EASYEDA online PCB simulator and designer. This is a fun project, mainly designed for changing or altering the voice. Generally, when we speak in a MIC we hear same voice. But in this project when we speak in MIC, we will hear a little bit different voice something like a robot is speaking. This can be used for doing prank or fun with your friends or can be used as a voice of your Robot.

Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are the important safety parameters. In this DIY session, we are going to build a Smoke Detector Circuit which not only sense the smoke in the air but also reads and displays the level of Smoke in the Air in PPM (parts per million). This circuit triggers the Buzzer when Smoke level becomes higher than 1000 ppm, this threshold value can be changed in the Code according to the requirement.

EasyEDA is a Cloud based free online service to design Circuit Schematics, simulate circuits, convert schematics into PCB Layout and manufacture PCBs for end users and industries. This all can be done at one place with EasyEDA online tool.

In this project I am going to share a LED Scroll Bar as shown in the above picture. Ten LED strips can flash in different effects by using an Arduino board. 


EasyEDA is a Online PCB design and Simulation Tool. We have already covered this tool in detail in this article EasyEDA for Electronic Circuit Design. Today, we will learn ‘How to use EasyEDA’ by designing and simulating the Simple 100 watt Inverter Circuit, with the help of Easy EDA.

Here's something interesting for the inner romantics and DIY circuit board assemblers among us. Yes, I'm talking to you, my friend; soldering iron in one hand, PCB board in the other, pining to tell your cherished special person how you feel about them, but clueless about how to express yourself. Sure, you could just tell them "I love you" — but words are nearly as cheap as fiberglass substrate and copper foil. Fine then, write them a card... but where's the pizzaz in that?!

EasyEDA is a free EDA tool for individuals and working in a web browser, it requires no any installation. It was designed to provide electronic hobbyists, engineers, teachers, students ... an easy and free access to the EDA. With EasyEDA, powerful schematic capture, mixed-mode spice simulation and PCB layout are made in your web browser. EasyEDA has all the features you expect  and easily take your design from conception through to production.
