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… |

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… |

LC Meter using Arduino: Measuring Inductance and Frequency All embedded lovers are familiar with multimeter which a great tool to measure voltage, current, resistance etc. A multimeter can measure them easily. But sometimes we need to measure inductance and capacitance which is not possible with a normal multimeter. There are some special multimeters that can measure inductance and capacitance but they are costly. We already built… |

Arduino Wattmeter: Measure Voltage, Current and Power Consumption As electronics engineers, we always depend upon meters/instruments to measure and analyse the working of a circuit. Starting with a simple multimeter to a complex power quality analysers or DSOs everything has their own unique applications. Most of these meters are readily available and can be purchased based on the parameters to be measured and their accuracy. But sometimes… |

Introduction to Bit Banging: SPI communication via Bit Banging Communication Interfaces are one of the factors that are considered when selecting a microcontroller to be used for a project. The designer ensures that the microcontroller being selected has all the interfaces required to communicate with all the other components to be used for the product. The existence of some of these interfaces, like SPI and I2C on microcontrollers,… |

DIY Self Balancing Robot using Arduino After being inspired by RYNO motors and other self-balancing scooters from Segway, I always wanted to build something of my own Arduino Segway Robot. Thinking for a while, I decided to build a Self Balancing Robot using Arduino. This way I would be able to grasp the underlying concept behind all these scooters and also learn how the PID algorithm works. … |

Controlling Arduino with Raspberry Pi using pyFirmata Although Raspberry Pi and Arduino are two different hardware in terms of their applications and structure, but they both are considered as two competing open source hardware platforms. They both have very strong community and support. Today we will slightly change things, and show you how we can take advantage of both of them. If you have both Arduino and… |

Arduino Based Real-Time Oscilloscope The Oscilloscope is one of the most important tools you will find on the workbench of any electronics engineer or maker. It is primarily used for viewing waveform and determining voltage levels, frequency, noise and other parameters of signals applied at its input that might change over time. It is also used by embedded software developers for code debugging and technicians… |

Record and Play 3D Printed Robotic Arm using Arduino 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… |

Interfacing LabVIEW With Arduino In previous article of Getting Started with LabVIEW, we have seen about LabVIEW and how it can be graphically programmed and executed in computer (software level). Now in this article we learn about How to Interface LabVIEW with Arduino Board. Requirements To interface LabVIEW with Arduino, you require the following software’s and hardware’s, LabVIEW… |

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… |
