Arduino ISP – LOG

Arduino ISP - LOG So this Lazy Old Geek (LOG) has had a lot of trouble getting Arduino bootload on Atmega chips. I couldn’t get either of these to work with Arduino UNO Rev3. http://arduino.cc/en/Tutorial/ArduinoISP http://letsmakerobots.com/node/35649 So I developed a couple that worked for me: http://www.instructables.com/id/My-Arduino-Bootloader/ http://www.instructables.com/id/UNO-Bootloader-In-Circuit- ...

Making a Vibrator That Listens to Your Body

This project has been an astonishing little journey. Many of my previous projects were characterized by an amazing outpouring of effort to build something highly intricate and ultimately invisible. This is the opposite kind of project. A little bit of work and a little custom design to create something new and exciting that I can immediately use in my everyday life. It also happens to be a sex toy. In other ...

Arduino Buzzer Circuit

This article and circuit diagram show how to connect a buzzer to an Arduino when the buzzer operates at a different voltage to the Arduino. The buzzer may operate at 9V, 12V or some other voltage. Arduinos such as the Arduino Uno operate from 5V. All the voltages referred to here are d.c. voltages (direct current). The same circuit used here can also be used to operate a 5V buzzer when the buzzer draws more ...

Arduino Basics #5 – Add SD storage to Arduino

Arduino Uno’s microcontroller board is great, but the one thing it’s not overly generous with is storage. Having 32KB of program flash storage, 2KB of RAM and 1KB of programmable EEPROM space at your disposal is fine for many Arduino projects, but it’s not enough when you need to record data. But with a $2 microSD card reader module from eBay, you can quickly add up to 32GB of space. What’s more, FAT32 soft ...

How to Convert an Arduino into an AVR Flash Programmer

In case you don't have an AVR programmer but you do have an arduino, the arduino can be converted into an AVR flash programmer, meaning it can program bare AVR microcontroller chips. Say if you have an AVR chip and you want to program the chip, so that the program that you've written and compiled gets stored into the flash memory of the chip to be executed. The arduino, with some specific wiring, can act as ...

AVRSH: A Command Interpreter Shell for Arduino/AVR. using arduino

Ever wanted to be "logged in" to your AVR microcontroller? Ever thought it would be cool to "cat" a register to see its contents? Have you always wanted a way to power up and power down individual peripheral sub-systems of your AVR or Arduino in *real time* ? Me, too, so I wrote the AVR Shell, a UNIX-like shell. It's UNIX-like because it's reminiscent of the shell account you went out and bought to run your ...

3D AIR mouse | Arduino + Processing

3D AIR mouse | Arduino + Processing I'm an Industrial design student, and last year as part of a course called "Technology as RAW materiel" I built this project as my final work. I work most of the time with SolidWorks, a CAD software for design and engenering. Rotating a solid body on the screen is done using the middle mouse button. I was looking for something more intuitive. This is how I ended up doing ...

Arduino ISP (In System Programming) and stand-alone circuits

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 Reference that explains each possible use of the platform. But if w ...

Read analog data directly in Processing using arduino

This instructable presents a fast an easy way to use data received from an analog sensor in Processing. You will learn to utilize the Arduino and prototype electronic boards to read meaningful data from the environment. The sensors can be affected by the light, the orientation, or a user’s physical input. For this matter we will use photocell, accelerometer, and potentiometer. Step 1: Preparation steps 1. U ...

Arduino Morse Code Flaher using arduino

I am a big fan of programming but I like to keep it down to 555 timer but when it comes to complex functions like flashing a LED in a certain pattern programming is necessary.One day while surfing through the I came across something known as Morse code.I decided to read it and found it totally awesome.I tried to make it with an arduino and I was successful in doing so. And now here that project explaining w ...
