Add Linux, WiFi, Ethernet and USB to Arduino

Web site: http://www.dragino.com/products/yunshield/item/86-yun-shield.html Project Summary: The model of this shield named Yun Shield, the feature of this shield is as its name. User can add this shield into Arduino (Leonardo, UNO, MEGA2560 etc) and "turn" the Arduino into device which has similiar features as Arduino Yun: support remote upgrade and use the Bridge library. With this shield, user can easy t ...

Arduino based Graph

This example shows you how to send a byte of data from the Arduino to a personal computer and graph the result. This is called serial communication because the connection appears to both the Arduino and the computer as a serial port, even though it may actually use a USB cable. You can use the Arduino serial monitor to view the sent data, or it can be read by Processing (see code below), Flash, PD, Max/MSP, ...

Analog Read Serial using Arduino

This example shows you how to read analog input from the physical world using a potentiometer. A potentiometer is a simple mechanical device that provides a varying amount of resistance when its shaft is turned. By passing voltage through a potentiometer and into an analog input on your Arduino, it is possible to measure the amount of resistance produced by a potentiometer (or pot for short) as an analog va ...

Interfacing Electronic Circuits to Arduinos

Interfacing Electronic Circuits to Arduino In this instructable I use an example of interfacing an Arduino to an ARINC 429 transceiver in order to demonstrate the general process of interfacing an Arduino to electronic circuits so you can use these techniques on your own designs. An ARINC 429 bus is the most common data bus used on aircraft for computer to computer communications. The ARINC 429 bus operates ...

Arduino Keyboard Message Code

When the button is pressed in this example, a text string is sent to the computer as keyboard input. The string reports the number of times the button has been pressed. Once you have the Leonardo programmed and wired up, open up your favourite text editor to see the results. NB: When you use the Keyboard.print() command, the Arduino takes over your computer's keyboard! To insure you don't lose control of yo ...

USB Freeform using an Arduino

This is a project in attempting to improve it predecessor "Freeform Arduino" by putting it in an enclosure and having it serve the similar purposes as "Palm Arduino Kit" and "Palm Arduino II" which I can carry it in my pocket and be available to use, and to connect to easy available power source specifically USB port. . I designed this "USB Freeform Arduino" with USB connector to be enclosed inside a 35mm f ...

Power off from an Arduino Sketch using the Pololu Power Switch

If you need an Arduino to shut off from within your Sketch, this is the solution. We will explore wiring the Pololu Pushbutton Power Switch, programming the Arduino to shut off the power, and making the unit "power on" only. The Pololu Pushbutton Power Switch comes in two versions - the SV version geared towards 4.5V-20V range, and the LV which specifies 2.5V-7.0V range. I will use a 9V battery for this dem ...

Digital Read Serial using Arduino

This example shows you how to monitor the state of a switch by establishing serial communication between your Arduino and your computer over USB. Hardware Required Arduino Board A momentary switch, button, or toggle switch 10k ohm resistor breadboard hook-up wire Circuit image developed using Fritzing. For more circuit examples, see the Fritzing project page   Connect three wires to the Arduino board. ...

Hookup an LCD to an Arduino

Adding an LCD display to Arduino projects can add real value but the cost of doing so can be significant. Not a financial cost - you can pick up 16 (characters) x 2 (rows) LCD for as little as £3.50. The cost is the pin count it can take to drive them. Using the built-in LiquidCrystal Display library it can take as many as 6 pins! That does not leave much for your sensors, motors and other components. There ...

Arduino Switch Statement used with sensor input

An if statement allows you to choose between two discrete options, TRUE or FALSE. When there are more than two options, you can use multiple if statements, or you can use the switch statement. Switch allows you to choose between several discrete options. This tutorial shows you how to use it to switch between four desired states of a photo resistor: really dark, dim, medium, and bright. This program first r ...

Barcode Reading using Roborealm Output on Arduino LCD

This Instructable shows how to create a Barcode Reader using only a webcam together with Roborealm and Arduino. The webcam used in this demonstration is the Logitech Quickcam and the LCD screen is labelled, JHD162A. What you need for this project: 1. Arduino UNO 2. LCD 3. Roborealm 4. Potentiometer Step 1: Coding the Arduino First of all, start by coding the Arduino to successfully output words on the LCD. ...

Arduino-l3dgecomm – Integrating L3DGEWorld and Arduino

L3DGEWorld is a tool for monitoring and interacting with networks and computer systems. Within a 3D world, entities bounce, spin, scale and otherwise change. These entities all represent an entity in another context - be it a server, phone, router or other monitorable device. The visual transformations represent various characteristics of these entities, such as packets per second, CPU load, memory usage or ...
