Simple 555 based Tremolo Effect Schematic

As of now here's a quick schematic for the video shared on Reddit (post embedded below!). I will re-wrote this post in detail when I have time.

Reduce the value of C1 for faster tremolo or turn the potentiometer!
You can remove D1 once you've finished testing. The way in which circuit works is quite simple- The 555 produces a square wave in which the ON time is greater than the OFF time, this signal is inverted by an NPN transistor in the next section. And then finally, whenever the last LED(D2) glows, the LDR's resistance decreases and almost shorts the signal creating a superb tremolo effect!

Distortion Pedal Electronics (Explained for beginners!)

If you are into DIY guitar pedals and want to start designing your own effects, this article might help you open a few doors. I write this article as an EE student who earlier struggled with understanding these circuits and would often simply copy schematics off the internet. 

This article is intended for-
1. Absolute beginners who like tinkering with electronics
2. Anyone who has been learning analog circuits and is looking for a jumpstart project.

Also before I start I'd like to mention, for anyone who wants to get a rock-solid foundation in Analog electronics, I highly recommend reading the book, 'Electronic Principles' by AP Malvino and David Bates.

Distortion Pedals come in all flavors and sizes, however, how the distortion effect is achieved in any of the pedals is more or less similar. Let's first see how the output of the pedal compares to its input.

The raw signal coming from the guitar is first amplified a little, and then the peaks of the amplified signal are clip…

5 Effective Online Tools that will Spice up your Arduino Projects!

Arduino has made electronics projects easier than ever. The question now is- Can we make the process of building projects faster and more enjoyable? Let's have a look at some of the interesting softwares/online tools developed for the Maker Community to make tinkering more effective and documenting projects easier!

1. TinkerCad

TinkerCAD's recently created circuit simulator allows you to arrange your Arduino/Attiny circuits in an easy 'drag and drop' environment and test them virtually without having to make them. This can be really helpful, for testing projects that use components which you are yet to buy. And after all, who doesn't like tinkering?


Try out Tinkercad-Circuits here!

But that's not what Tinkercad is famous for. It offers an amazingly easy to use 3D design tool for Makers, once again in a simple 'Drag and Drop' interface! You can directly download the CAD file, once you're done designing. If you've ever thought of making your own uniqu…

TV Remote Controlled Servo Motor-Using Arduino!

Greetings!
We use our TV remotes to control the functions of the TV's, but when the TV is not in use, they're absolutely useless. Today, we are going to learn how to add more functionality to ordinary IR based remotes, in this one we shall see how to control servo motors. There are so many (SO MANY) different applications of this project that one can think of. Using the following tutorial, you can make one yourself!

1. Watch the video tutorial-


2. Things you will need-

Note that you may use a different IR receiver other than TSOP1738, if it isn't available. Usually you can find this on websites like amazon and ebay.
3. The circuit diagram!

4. The IR Remote Library http://z3t0.github.io/Arduino-IRremote/
5. The Arduino Code- Just copy paste this code into your Arduino IDE
