Modern Device

Eagle CAD or Eagle PCB or just Eagle is the electronic design automation (EDA) software package that most hobbyists and beginners use. Some of this blog post is probably useful to Eagle beginners, or people just learning the package. Other parts of it are only going to be understood thoroughly by people who have used Eagle for a while, and experienced its mysteries. This is NOT a tutorial on how to begin using Eagle, there are lots of excellent ones on the web. Not too many of them actually take a critical attitude toward Eagle though, and ask why things are the way they are. Newark Electronics bought Eagle about six months ago, so perhaps they are ready to throw a little money at CadSoft to move Eagle a little closer to modern EDA software packages.

TVout Light Pen Demo Arduino TVout Light Pen Demo focalist: So, here to prove that we can take decades-old technology and re-use it, poorly... The Arduino Light Pen! Another fun little TVout project, I'm now coming up with a few improvements and seeing what kind of interesting and fun uses this little HID blast from the past can give us... I'll be documenting it up shortly, but you really don't get much simpler! Snap Circuits Jr. 100-in-1 SC-100 Snap Circuits Jr. 100-in-1 includes over 30 plastic parts and over 100 sample projects. The snap-together electronic blocks are mounted on plastic pieces that can be used again and again to form many exciting and educational circuits. Winner of the Dr.

Arduino Arduino is an open-source computer hardware and software company, project and user community that designs and manufactures kits for building digital devices and interactive objects that can sense and control the physical world.[1] Arduino boards may be purchased preassembled, or as do-it-yourself kits; at the same time, the hardware design information is available for those who would like to assemble an Arduino from scratch. The first Arduino was introduced in 2005. The project leaders sought to provide an inexpensive and easy way for hobbyists, students, and professionals to create devices that interact with their environment using sensors and actuators. Common examples for beginner hobbyists include simple robots, thermostats and motion detectors. AccelStepper: AccelStepper library for Arduino This is the Arduino AccelStepper library. It provides an object-oriented interface for 2, 3 or 4 pin stepper motors. The standard Arduino IDE includes the Stepper library ( for stepper motors.

Using Relays with Arduino – Turning on the Lights Warning!!! This project deals with AC electricity which is dangerous if you don’t know how to treat it safely. You must treat electricity with caution. There are many books and websites about electrical safety procedures and if you’re not sure how to be safe you should read that information. The most basic advice I can give is always assume any exposed wires are live and touching them will hurt a lot at best and kill at worst. Microcontrollers are good at controlling small devices, but frequently we DIY-ers want to use them to control things that aren’t so micro. LPC2148 ADC Example: Nintendo DS Touch Screen > Using ADC to measure the current X/Y position on a Nintendo DS touch screen Resistive touch screens can be a great way to enable complex user input in your projects inexpensively and with a minimum number of pins. With just four wires you can capture gestures, buttons clicks, constantly track the position of a finger or stylus, and other interesting things. Best of all ... thanks to the success of current touch-enabled devices like the Nintendo DS, there is also a steady supply of inexpensive touch screens available (which is precisely why we've chosen to use the Nintendo DS touch screen as an example). Resistive touch screens operate on the same principle as a simple potentiometer ... you apply 3.3v and GND on opposite ends, and measure the resulting current in between the two on a third pin (using an analog to digital converter). The only difference is that rather than adjusting the resistance by turning a dial, you adjust it by touching a certain part of the screen.

Bionic Arduino – Introduction to Microcontrollers with Arduino Bionic Arduino is a set of four 3-hour classes in November 2007 hosted by Machine Project and taught by Tod E. Kurt. It is an introduction to microcontroller programming and interfacing with the real world using the Arduino physical computing platform. It focuses on building new physical senses and making motion with the building blocks of robotics, using Arduino as a platform. In the class, participants are shown and experiment with the Arduino’s capabilities and learn the basics of common microcontroller interfacing, such as: digital output to control lights and LEDs, digital input to read switches and buttons, analog output to control motor position or LED brightness, and analog input to read sensor inputs.

Martijn Thé – iPhone & iPad Development & Interaction Design » Interfacing an optical mouse sensor to your Arduino In this tutorial I’ll describe how you can connect the optical sensor inside a cheap mouse to your Arduino and have it read out the x- and y-movements. This will enable your Arduino to handle mouse input, detect surface movements, measure surface speed, etc. Materials This is what you need: Arduino board (any *duino will do) and the Arduino IDE.Optical mouse containing the PAN3101, ADNS-2610, ADNS-2083 or ADNS-2051 optical sensor. These sensors come in many mice sold today.

Wiring a 12 V Switch and LED to a 5 V Circuit The previous page discussed the inability to rewire the insides of a 12 V illuminated toggle switch to make it compatible with 5 volts. The toggle switch either provides 12 V when switched on, or nothing (not ground) when switched off. We want to connect this to a 5 V microcontroller input to detect the position of the switch. If the 12 V switch were wired directly to the microcontroller input, the 12 V power source would damage the 5 V microcontroller.

Temperature Sensor + Arduino « DanielAndrade.net Hello people, it’s been a while since I have posted projects on this website. This semester was really busy, I didn’t have time to much else, but soon I will have my winter holiday (Here in south our summer holiday is from December to February). Today I am going to show you how to build a simple temperature sensor using one LM35 Precision Temperature Sensor and Arduino, so you can hookup on your future projects. The circuit will send serial information about the temperature so you can use on your computer, change the code as you will. I’m planning to build a temperature sensor with max/min + clock + LCD, and when I get it done, I will post here. Parts:
