We use an Arduino to program other ATmega without bootloader . This technique allows you to use all flash memory for code and make boards using new ATmega, cheaper than those with bootloader. The qualities that have made the success of Arduino are undoubtedly the open-source software, many libraries, a good hardware and a virtually infinite […]

Hi All! I have wanted to do something fun with my bedroom for a while now and the Make it Glow challenge provided me with a reason to do so. A few months ago I acquired a strand of GE-35 Color Effects lights and owing to the inherent dangers of controlling wall voltages, the strand
RGB LEDs are fairly useful in projects allowing for a wide range of color from a single unit. However they can be a pain in the neck to work with and they too often come with little or no documentation. I searched for some time to find a common resource on them and this Instructable

My DIY Oscilloscope, how i got my signal Content : – Description – Screenshots – Video – Credits and links Descriptions I am experimenting with RF and IR signals in various frequencies and had some trouble with the receivers and needed to see what kind of signal i was receiving. I cannot afford a real

Overview In this lab, you’ll learn how to connect a variable resistor to a microcontroller and read it as an analog input. You’ll be able to read changing conditions from the physical world and convert them to changing variables in a program. (:toc Table of Contents:) Parts For this lab you will need to have
Make PPE milk bottles into good looking LED lights, and use an Arduino to control them. This recycles a number of things, mainly the milk bottles, and uses a very low amount of power: the LEDs apparently dissipate less than 3 watts but are bright enough to see by. Among other things, I wanted to
Addressable Milk Bottles (LED Lighting + Arduino) using arduino Continue Reading
Origami is the traditional Japanese art of paper folding. In this project, with a little help from an Arduino, you can bring your origami into the 21st century and make it an interactive art! The result shown here uses Bare Conductive paint to give an origami flower proximity sensing powers. When you put your hand
Proximity Sensing Origami Flower using Arduino Continue Reading
When I first became aware of Arduino, a theremin seemed like a natural project: sensor + actuator. It turned out to be quite affordable and fun to make. It is a naive design, using just one photocell and some hacked headphones. After some experimentation, I decided that a self-calibrating function was essential if I wanted
Charlieplexing is an ingenius method for controlling many LEDs without using many microcontroller pins. You can turn on or off one LED at a time. To light more than one LED at a time, you can scan the LEDs by turning a sequence of them on and off really fast. The number of LEDs you
Step 1: Check the materials you need. Below is the list of stuff you need to make it: 1. Arduino I used an Arduino Pro Mini 3.3V. You also need USB-Serial tether to program it. 2. A battery box I used a AA x 4 battery box with power line wires. 3. Breadborad I used
