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.

Set Up a Minecraft Server on Your Raspberry Pi

Set Up a Minecraft Server on Your Raspberry Pi

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.

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.

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.

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.

DIY Wi-Fi Jammer using NodeMCU ESP12

There is a Wi-Fi protocol called 802.11 which act as a deauthentication frame. This is used to safely disconnect all the users connected with the router. To disconnect any device from some Wi-Fi network, it is not important to know the password or to be in the network, you just need mac address of the Wi-Fi router and client device and it is enough to be in its range of that Wi-Fi network.

Push-Pull Amplifier Circuit

Push-Pull Amplifier is a power amplifier which is used to supply high power to the load. It consists of two transistors in which one is NPN and another is PNP. One transistor pushes the output on positive half cycle and other pulls on negative half cycle, this is why it is known as Push-Pull Amplifier. The advantage of Push-Pull amplifier is that there is no power dissipated in output transistor when signal is not present.

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 Arduino Motor Driver Shield

DIY Arduino Motor Driver Shield

In this DIY session, we make an Arduino Motor Driver Shield to drive DC motors, stepper motor and Servo Motor. Compatible with Arduino UNO and Arduino Mega, this motor driver shield can operate 4 DC motors or 1 stepper motor and 2 servo motors at a time. Here two L293D Motor Driver ICs are used for driving motors and an 8-bit shift register for controlling them.

Interfacing Flame Sensor with Arduino to Build a Fire Alarm System

In this article we interface Flame Sensor with Arduino and learn all the steps to build Fire Alarm System by using Arduino and flame sensor. Flame sensor module has photodiode to detect the light and op-amp to control the sensitivity. It is used to detect fire and provide HIGH signal upon the detection. Arduino reads the signal and provides alert by turning on buzzer and LED. Flame sensor used here is an IR based flame sensor.
