Hello, I’m David and in this instructable I’ll show how I made this hexapod whose name is Hexdrake. Since I was 16 I became interested in electronic and later in robotics. After getting some level and programming skills using arduino I decided to build a robot something more interesting than a simple robot with two […]

Connect the Arduino outputs with 5 volt power to the relay coils. Use a separate 9 or 12 volt battery for powering the motor.  Connect the 9 or 12 volt power to the relay contacts and the motor.  Be sure to avoid connecting the 9 or 12 volt power to any of the Arduino input […]

Arduino Tutorial #1 – Getting Started and Connected! In this video I cover the following: * What is Arduino? * What is a sketch? * What is the Arduino (software) IDE (interactive development environment) arduino-1.0.1 * Arduino philosophy * We take a look at the Arduno hardware. * I cover how to download the Arduino […]

Quit pulling your hair out over incorrect passwords. Using an Arduino Leonardo and Adafruit’s NFC shield, you can unlock your computer with an NFC card. The Arduino reads the NFC card’s unique identifier and once it receives the correct one, it uses the Arduino Leonardo’s keyboard emulation feature to type a password. Step 1: Parts […]

What is Arduino? Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. It’s an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board. Arduino can be used to develop interactive objects, taking […]

Winter is coming. So it is time to make preparations. If you live in a colder climate, you need to be concerned about the possibility of your pipes freezing. There are a lot of preventative measures that you can take such as insulating your pipes and leaving the water dripping. But for a little extra […]

Introduction Contents [hide] 1 Introduction 2 What You’ll Need to Know 3 Things You’ll Need 4 Connect the temperature sensor 5 How the Temperature Sensor Works 6 Install the External Libraries 7 Program the Microcontroller 8 Conclusion In this lab, you’ll see synchronous serial communication in action using the Inter-integrated Circuit (I2C) protocol. You’ll communicate with an […]

The AD8237 is a micropower, zero drift, rail-to-rail input and output instrumentation amplifier. The relative match of two resistors sets any gain from 1 to 1000. The AD8237 has excellent gain accuracy performance that can be preserved at any gain with two ratio-matched resistors. The AD8237 employs the indirect current feedback architecture to achieve a […]

This is a set of simple, small form-factor, mini-shields that I created almost by accident. As I made more and more of them, I realized that they could be really useful. What started out as a way to use some spare parts, turned into a standardized form factor for a versatile, miniaturized Arduino shield. The […]

Codebender is a web-based programming tool for Arduino. ” Traditionally, you would need to install an IDE, which includes all the necessary software, find and install the correct drivers, set permissions, etc. It can take 10-60 minutes. Or it can be a total mess. With Codebender, you can program your Arduino straight from your browser. […]
