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.

Analog Speedometer Using Arduino and IR Sensor

Analog Speedometer Using Arduino and IR Sensor

Measuring the speed/rpm of a Vehicle or a motor has always been a fascinating project to try. In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Sensor module to measure the speed. There are other ways/sensors for this, like hall sensor to measure speed, but using an IR sensor is easy because IR sensor module is very common device and we can get it easily from the market and also it can be used on any type of motor/Vehicle.

Self Balancing Robot using Arduino

Self Balancing Robot using Arduino

Once I started building the self balancing robot, I realized that this bot is a bit of a challenge to build. There are so many options to select from and hence the confusions start right form selecting the motors and remains till tuning PID values. And there are so many things to consider like type of battery, position of battery, wheel grip, type of motor driver, maintaining the CoG (Centre of gravity) and much more.

But let me break it to you, once you build it you will agree that it’s not as hard as it sounds to be. So let’s face it, in this tutorial I will document my experience in building the self balancing robot. You might be an absolute beginner who is just getting started or might have landed up here after a long frustration of not getting your bot to work. This place aims to be your final destination.

I think my robot dog walking service just needs a little more tuning.

Controlling Arduino with Raspberry Pi using pyFirmata

We use PyFirmata firmware to give commands to Arduino using Raspberry Pi python script. PyFirmata is basically a prebuilt library package of python program which can be installed in Arduino to allow serial communication between a python script on any computer and an Arduino. This python package can give access to read and write any pin on the Arduino. So here we will run python program on Arduino using Raspberry pi.

So in this tutorial we will take advantage of this library and will use this in our Arduino board to control Arduino using Raspberry Pi.

Programming STM32F103C8 Board using USB Port

Programming STM32F103C8 Board using USB Port

In our previous tutorial we learnt the basics of the STM32 Development Board and also programmed it to blink an LED. But there was one huge drawback with it. In order to program the Board we utilised a FTDI programmer module and also had to toggle the boot 0 jumper between and 1 position while uploading and testing a code, which is surely a daunting task. Also the mini-USB port on the Development board was left totally unused. The reason for doing that is, when the STM32 development board is purchased it does not come with an Arduino ready boot loader and hence the board will not be discovered by your computer when connected through the USB.

Arduino Based Real-Time Oscilloscope

Today I will be demonstrating how to use the Arduino and a software, which will be developed with my favourite programming language Python, to build a low cost, 4-channel Arduino oscilloscope capable of performing the tasks for which some of the cheap oscilloscope are deployed like the display of waveforms and determination of voltage levels for signals.

Automatic Water Dispenser Project

Automatic Water Dispenser Project

It might not appear big at the first time, but if your tap dripped a drop of water once every second it would take only about five hours for you to waste one gallon of water, that is enough water for an average human to survive for two days. So what can be done to stop this? As always the answer, for this, lies with improvement in technology. If we replace all the manual taps with a smart one that opens and closes on its own automatically not only we can save water but also have a healthier lifestyle since we don’t have to operate the tap with our dirty hands. So in this project we will build a Automatic Water Dispenser using Arduino and a Solenoid valve that can automatically give you water when a glass is placed near it. Sounds cool right! So let’s build one…

DIY Record and Play 3D Printed Robotic ARM

DIY Record and Play 3D Printed Robotic ARM

Robotic Arms have proved themselves useful and more productive in many applications where speed, accuracy and safety is required. But to me, what’s more than that is these things are cool to look at when they work. I have always wished for a robotic arm that could help me with my daily works just like Dum-E and Dum-U that Tony stark uses in his lab. These two bots can be seen helping him while building the Iron man suits or filming his work using a video camera. Actually Dum-E has also saved his life once……. and this is where I would like to stop it because this is no fan Page. Apart from the fictional world there are many cool real world Robotic Arms made by Fanuc, Kuka, Denso, ABB, Yaskawa etc. These robotic arms are used in Production line of automobiles, mining plants, Chemical industries and many other places.
