In this project, we will show how to connect multiple I2C devices to an arduino microcontroller. The I2C bus is a bus which enables high-speed two-way communication between devices while using a minimal number of I/O pins to facilitate communication. An I2C bus is controlled by a master device (usually a microcontroller) and contains one […]

So back when I first started working with micro controllers, Arduinos mainly the most annoying this ever was when i would follow someones tutorial for a project and they would use the Arduino uno, I would be using the Arduino micro or something, i would spend like an hour wiring it up following the instructions
Can I Use an Arduino Uno for This? Continue Reading
Today, we are going to build a circuit to program an ATtiny85 with our Arduino. Supplies We are going to need the following: Some jumper wires 1 x 10 micro farad capacitor The ATtiny85 Chip A breadboard An Arduino For Extra visual’s (that are not really required) I’m going to add: 3 LED’s 1 x

Keyless piano using Arduino is sort of sequel to the DIY fun piano i have published in this website. In this project i have eliminated the need of buttons involved to play the piano. Here i have used IR in place of buttons. Let’s get into the construction and building part of this project. Read

Everything around us is getting smart shoes, watches glasses. Even you might have come across news regarding smart vehicles in newspaper. Likewise we attempted to create a prototype of smart vehicle using Arduino. Let’s get into the building part of our smart vehicle. INPUT PERIFERALS: Potentiometer – For Controlling the speed of our vehicle L293D

A range finder is a device used to find the distance from a point to the nearest obstacle. This device uses ultrasonic technology to measure the distance. You can consider it like an electronic, hassle-free version of a measuring tape with a measuring range of 2cm to 400cm and an accuracy of 1cm. Typical applications

This Arduino project is a simple and fun project you can build in 10-15 minutes. The result of this make will be an Arduino audio player that plays “.wav” files. It consists of a speaker, a simple transistor acting as an amplifier, and a micro-SD card adapter with a micro-SD card in it where the .wav

In this tutorial we are going to design a Barometric Pressure Measuring System using BMP180 and ARDUINO. First of all for interfacing BMP180 to ARDUINO, we need to download a library specifically designed for BMP180. This library is available at: https://github.com/adafruit/Adafruit-BMP085-Library After attaching that library, we can call special functions which will ease working with BMP180

In ARDUINO we have 20 I/O pins, so we can program 20 pins of UNO to be used as either input or output. Although there are more pins on ATMEGA328P controller than on UNO, this is because while designing the board some pins are defaulted. Now for some applications we need more than 30 pins, say

In this tutorial we are introducing concept of ADC (Analog to Digital Conversion) in ARDUINO UNO. Arduino board has six ADC channels, as show in figure below. Among those any one or all of them can be used as inputs for analog voltage. The Arduino Uno ADC is of 10 bit resolution (so the integer values
