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.
