Arduino Based Guitar Tuner

Hi guys, during the last few weeks, I’ve been working on reconnecting with my love for the guitar. Playing the box guitar was how I relax few years back before the saxophone took over. Going back to the guitar, after 3 years of rarely strumming a chord, I discovered amongst other things that I no longer knew how each of the string should sound, to put it in my friend’s words, “My hearing was no longer tuned” and as a result of this, I was not able to tune the guitar without the aid of a keyboard or a mobile app which I later downloaded. The weeks went by till few days ago when the maker in me became motivated and I decided to build an Arduino based Guitar Tuner. In today’s tutorial, I will be sharing how to build your own DIY Arduino Guitar Tuner.

Arduino Calculator using 4×4 Keypad

In this tutorial we will build our own calculator with Arduino. The values can be sent in through a keypad (4×4 keypad) and result can be viewed on a LCD screen (16×2 Dot-matrix). This calculator could perform simple operations like Addition, Subtraction, Multiplication and Division with whole numbers. But once you understand the concept you can implement even scientific functions with Arduino’s built in functions

DIY Fire Fighting Robot

DIY Fire Fighting Robot

In this project, we will learn how to build a simple robot using Arduino that could move towards the fire and pump out water around it to put down the fire. It is a very simple robot that would teach us the underlying concept of robotics; you would be able to build more sophisticated robots once you understand the following basics.

DIY Arduino CNC Machine

This DIY Arduino CNC Machine can draw most of the basic shapes, texts and even cartoons. It’s operation is similar to the way a human hand writes. It’s faster and more accurate compared to the way a human being can write or draw. Check the demonstration Video below:

Arduino Motion Detector Alarm

With the help of the PIR Sensor it has become very easy to detect human/animal movements. In this project we will learn how we can interface a PIR Sensor with a microcontroller like Arduino. We will interface an Arduino with PIR module and blink a LED and beep a Buzzer whenever a movement is detected.

Arduino Data Logger

As Engineers/Developers we always rely upon the data collected to design or improve a system. Recording data and analyzing them is a common practice in most of the industries, here we are building Arduino Data Logger Project where we will learn how we can log data at a specific interval of time.

Interfacing OLED with Arduino

The term OLED stands for “Organic Light emitting diode” it uses the same technology that is used in most of our televisions but has fewer pixels compared to them.  It is real fun to have these cool looking display modules to be interfaced with the Arduino since it will make our projects look cool. We have covered a full Article on OLED displays and its types here.
