How to build a 5$ Arduino (clone) | Hardware Startup If you are like me and build projects with Arduino, you must have felt the frustration with ripping your project apart, because you wanted to build something else with that Arduino. I have had the same issue many times, so I decided to find a way to solve this once and for all. Hence, how to build an Arduino clone for less than 5$. Warning: Now before we continue a warning. This post explains how to build Arduino cones for less than 5$, but it will mean that you either get creative with you current Arduino to program the Arduino bootloader, or you invest a bit in a standalone ISP programmer and a FTDI interface board (total about 20$ one time investment). The reason we can build a relative cheap Arduino clone is that Arduino consists of the following parts: - USB to serial converter (also known as FTDI) - ATMEGA328p with oscillator and bootloader - 5V power circuit - Bunch of headers So where do I get these cheap ATMEGAs? Like this: Like Loading...
Arduino vs Picaxe Should I go for Arduino or Picaxe for my next robot? (EDIT: Please note that this is a very old post, things have changed :) Let´s compare: Scalability: ****************** Picaxe run on many different chips, all from the company called Microchip. ****************** The proto board for the picaxe is valued high, it actually makes the difference - you can build a robot just by adding motors and sensors, it is robot-ready! Picaxe: 2 points Arduino:0points ================== Speed: ****************** Picaxe can run from 4 to 16 Mhz, but if you plan to use Picaxe Basic, you are best off using 4 Mhz ****************** Arduino runs on 16 Mhz ****************** Although not many robotic projects will have a processor- speed-issue (or they should use co-processors if speed really did matter), and although the Picaxe can run at the same speed, Arduino wins the speed-contest Picaxe: 0 points Arduino:1 points ================== Picaxe: 1 points Arduino:1 points ==================
Don't Spend Money On An Arduino - Build Your Own For Much Less I love my Arduinos. At any point, I have quite a few projects on the go – prototyping is just so easy with them. But sometimes, I want to keep the project functional without buying another Arduino. The Truth: You Can’t Build a Full Arduino Clone For Cheaper The Arduino itself consists of simple electronics, but it’s the package and the layout you’re really paying for. The beauty of building your own is that you can exclude bits you don’t need to keep costs down, and avoid the Arduino package with all the unused headers and wasted space – if you really need the Arduino shape and headers for use with other shields, then building your own isn’t really going to save you any money. In my case, I wanted to permanently display the LED cube I made somewhere, with an external power supply and not the added cost of using a full Arduino board; there was space left on the protoboard after all, so I’d rather put everything there. Anyway, on with the project. Power Supply Regulator & Indicator LED 1.
What is Nanode | Nanode In a nutshell, Nanode is an open source microcontroller board which has on-board internet connectivity. It is a low cost building block to allow experimentation with the Internet of Things. If you are familiar with Arduino, then you will recognise Nanode as the next logical step in the creation of exciting open source hardware projects – ones which can interact with cloud based applications and events in the online environment. If you are a newcomer to Arduino, may I suggest that you look at this excellent Arduino primer. Arduino has to be the “poster-child” of the open source hardware community – and as the project has been embraced and expanded to a larger community in recent years, it is a natural development that new ideas arise from the original design. Arduino is essentially an 8-bit microcontroller which communicates almost exclusively via a simple serial com port connection, normally to a laptop or PC.
Use Android’s chronometer timer widget for your apps Look at this demonstration of Android's chronometer widget, and see if it's the right tool for the job. One thing all computing platforms have in common are timers. In fact, every compute platform I've worked on has at least half a dozen kinds of timers. Android is no exception. This tutorial demonstrates Android's chronometer widget. 1. 2. main.xml <LinearLayout xmlns:android=" xmlns:tools=" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:gravity="center"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Chronometer Demo" android:textSize="20sp"/> <LinearLayout android:orientation="horizontal" <Button android:text="START" android:id="@+id/start_button" android:layout_height="wrap_content"/> android:text="STOP" android:id="@+id/stop_button" <Chronometer android:id="@+id/chronometer" android:format="%s" 3.

Interfacing a sensor with an Arduino The world of hobby electronics is one that has seen explosive growth and massive changes over the past few years. The biggest changes have come from the level of computing hardware that is available to the hobbyist. From very simple microcontrollers to full PCs on a USB stick, all sorts of options are available. One of the more popular options is the Arduino, which falls between these two extremes. The entire Arduino project has been a proof of the power of open source. In this tutorial, you will get a development environment set up to work with your Arduino. Resources ArduinoArduino Playground Step by Step Step 01 Get your hardware The first step is to select your hardware. Step 02 Plugging in Most Arduino boards interface over USB with the development computer. Step 03 Software Installing the required software has gotten much easier recently. Step 04 Start a new program Now that you have your Arduino plugged in, you can start up your IDE and begin programming your first project. Step 05 Step 06
11 Arduino projects that require major hacking skills—or a bit of insanity Raspberry Pi has received the lion's share of attention devoted to cheap, single-board computers in the past year. But long before the Pi was a gleam in its creators' eyes, there was the Arduino. Unveiled in 2005, Arduino boards don't have the CPU horsepower of a Raspberry Pi. They don't run a full PC operating system either. Arduino isn't obsolete, though—in fact, its plethora of connectivity options makes it the better choice for many electronics projects. While the Pi has 26 GPIO (general purpose input/output) pins that can be programmed to do various tasks, the Arduino DUE (the latest Arduino released in October 2012) has 54 digital I/O pins, 12 analog input pins, and two analog output pins. Arduino's array of inputs and outputs proves crucial in projects from building robots to 3D printers, said Jason Kridner, co-creator of the BeagleBone line of products that combine Raspberry Pi-like horsepower with Arduino-like capabilities. Dublon spent a year testing Tongueduino on himself.
Build a bare bones Arduino clone which maximizes its use of real estate Check out all the stuff crammed into a small swath of strip board. It’s got that characteristic look of a roll-your-own Arduino board, which is exactly what it is. [S. The strips of copper on the bottom of the substrate run perpendicular to the DIP chip and have been sliced in the middle. Pin headers along either side of the board have been altered to allow for soldering from the wrong side of the plastic frames. Ringing in at as little as $2-$4.75 a piece you’ll have no problem leaving this in a project for the long hall.

Arduino - Wikiwand Open source hardware and software platform Arduino () is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Its hardware products are licensed under a CC-BY-SA license, while software is licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL),[1] permitting the manufacture of Arduino boards and software distribution by anyone. The Arduino project began in 2005 as a tool for students at the Interaction Design Institute Ivrea in Ivrea, Italy,[2] aiming to provide a low-cost and easy way for novices and professionals to create devices that interact with their environment using sensors and actuators. The name Arduino comes from a bar in Ivrea, Italy, where some of the founders of the project used to meet.
