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.

Minecraft is one of the most popular game in the world and people are getting additive for this interesting game. You can setup your own Minecraft server and can create your own worlds in the game. For this, you don’t need to spend money on a dedicated PC, it can be easily done with a small, credit card-sized Linux computer Raspberry Pi. If you want to play it on small LAN network with your family and friends then Raspberry is the perfect choice for you. Graphics of this game is not good but still it looks so fascinating to play this game on network with other people.
Setup your own Miinecraft server on your Pi:
A Power supply unit is a very commonly used tool by most engineers during the development stage. I personally use it a lot when experimenting with my circuit designs on Breadboard or to power up a simple module. Most of the digital circuits or embedded circuits have a standard operating voltage of either 5V or 3.3V, so I decided to build a Power supply which can supply 5V/3.3V on the power rails of the breadboard and fits snugly on the breadboard.
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.
