Blog Archive » Arduino-controlled IKEA Lamp Posted by adminon September 07, 2009Arduino, Projects This is a project I have been working on for the past 2-3 weeks. I wanted to create a night light which had to be very simple to use and with no parts that can be consumed by babies! I used 20 RGB LEDs (which I got from www.oomlout.co.uk), an old Eriksson phone charger and, of course an arduino board (actually I used an old SparkFun clone).
Laser Flashlight Hack!! Turn a MiniMag flashlight into a powerful DVD laser pointer! This 245mw laser is powerful and fits real cozy in a MiniMag! See the video at the end for the Test Results! NOTE: This Instructable WILL NOT WORK with any CD burner/player diodes or DVD player diodes! See the FAQ on the last Step for common questions UPDATE: If you want to use this as more than just a novelty item, a driver circuit is recommended.
Arduino Digital Vibration Sensor module - Geeetech Wiki Introduction The Arduino vibration sensor module is based on vibration switch component which can detect the weak vibration signals. The sensor can work for vibration-related modules. Preparing for a week with Windows 7 photo credit: mnadi Starting tomorrow, I will be embarking on a week long venture of using only Windows 7. I downloaded the beta version of Microsoft’s next Windows release immeadiately after it was made available in January. However, since I installed it on my presentation laptop, I don’t use it very often.
arduino meets processing - PUSHBUTTON The Arduino meets Processing project intends to make it as easy as possible for anyone to explore the world of physical computing. All you need is an Arduino board as well as the Arduino and Processing software, which you can download on their project websites. On this website we explain how to: set up electronic circuits with various kinds of sensors, control and measure the sensors with the Arduino board, send the data to the computer, and use the received values to generate computer graphics with Processing. Arduino mood light I recently saw the cool mood lamp by Philips and I liked it. What I did not like was the price. I set myself to discover what the industry has to offer in terms of high-power LEDs. It turns out that since the old 20mA red LEDs the market has evolved in such a way that it seems the light appliances of the future might be completely LED-powered.

Creating custom character: LCD Tutorial for interfacing with Microcontrollers - 8051 Microcontroller Projects AVR PIC Projects Tutorials Ebooks Libraries codes As already explained, all character based LCD of type HD44780 has CGRAM area to create user defined patterns. For making custom patterns we need to write values to the CGRAM area defining which pixel to glow. These values are to be written in the CGRAM adress starting from 0x40. If you are wondering why it starts from 0x40? Then the answer is given below. Bit 7 is 0 and Bit 6 is 1, due to which the CGRAM adress command starts from 0x40, where the address of CGRAM (Acg) starts from 0x00.
Why Linux Doesn’t Spread - the Curse of Being Free Sharebar Linux isn’t very popular on the desktop. It’s a far third behind OS X, which is a very far second behind Windows. Spooky Projects – Introduction to Microcontrollers with Arduino Spooky Projects is a set of four 3-hour classes in October 2006 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. 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. From these tools all sorts of interesting projects can be created. In the class, a few simple project sketches are covered using the provided parts kit, under the theme of spooky animatronics for Halloween.
Schematic of 8x8 Led Dot Matrix Clock using PIC16F627A The above schematic is 8x8 Led Dot Matrix clock using PIC16F627A (or PIC16F628 which is more expensive but larger memory) and a shift register 74HC595. The PIC is running with 4MHz internal oscillator so pin 15 (RA6) and 16 (RA7) are free. Therefore, the PIC16F627a can drive the 8x8 Led Drive matrix with these 2 free pins (RA6, RA7) and RB0-5, . The Timer1 (TMR1) external clock is generated by the watch crystal 32.768KHz + load capacitors 15pF and fed to RB6 and RB7. The pins are used up!. Method of setting time is similar to the 5x7 Led Dot Matrix Clock.
