I’m currently working on a project that requires a cheap, low-power microcontroller that’s programmable through Arduino and has a few more pins than the ATtiny85. That’s where I found the ATtiny84A. It has many of the same features as the ATtiny85, but has 12 I/O pins instead of six.

This tutorial shows some of the basic capabilities of an Arduino and it’s integration with Ubidots. After doing it, you'll learn what an Arduino is, what it does and how you can set it up to turn an LED (or any other actuator) on and off from your Ubidots account. All you need to get started is an Arduino board and the official Arduino WiFi Shield.

This is a cool DIY project for makers where we design a speedometer for bike using arduino and 3D printed box. The speed of the bike can be viewed on an android phone.

This is an interesting project in which we explore the power of an Arduino and Android to create a Surveillance device which uses Arduino and Ultra Sonic Sensor to broadcast the information to a mobile application (Android) using Bluetooth.

In this tutorial, we design an Arduino Uno Robotic Arm. Entire arm will be designed from some scrap material and servos. Entire process of construction has been explained in detail below.

I wanted to make an audio player using an arduino but I didn't have an microsd card reader or an mp3 decoder chip.

NeoPixel LED Strip requires only three pins to drive several RGB NeoPixel LEDs. Two pins are for power and ground and one Pin is for Data In (DI). Data IN pin is used to address and control the different LEDs in the strip with their color, brightness etc.

Here GSM Module is used to Make the Call, answer the Call, send SMS, and read SMS, and also this Arduino phone has Mic and Speaker to talk over this Phone. This project will also serve as a proper interfacing of GSM Module with Arduino, with all the Code needed to operate any Phone’s basic functions.

In this tutorial, we will build a lightning detector using an Arduino Uno, a few resistors and some jumper wires. Most lightning detectors often cost too much for the normal hobbyist, however this does not mean one cannot enjoy lightning detection and the physics behind it.

We have built a Scientific calculator having lots of functions like

Basic algebraic operations (+, -, *, %)
Trigonometric functions (SINe, COSine, TANgent)
Inverse trigonometric functions (arcSin, arcCos, arcTan)
Logarithmic function
Square root.
