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 […]

In this tool-assisted education video I show how to program an Arduino Atmega2560 board in C++11 to dump a ROM chip, such as a 386sx BIOS or a Famicom cartridge ROM. I also make a ZMODEM sender and a LED blinker in this video. Sorry about the bad dub / lipsync in the beginning. I

Hi. This Instructable will guide you through the process of wirelessly programming your Arduino using two XBees. I just finished designing a wireless EEG system with the XBee modules, so I’ve become quite fluent in their programming and have just now been able to accomplish this. It still amazes me how difficult it has been to try to wirelessly

I’m working on an Arduino clone. The Arduino is essentially an ATMEGA328P development board with a bootloader pre-loaded. There are a lot of custom macros built into the programming interface that make it really easy to use, and even easy to build some powerful applications. Arduinos have taken off and can be found everywhere, doing

I’ve found several sites and posts explaining how to use a quadrature encoder with an Arduino, but wasn’t completely satisfied with any of the methods used. Perhaps part of the problem is with the encoder I’m using: it’s part #COM-09117 at Sparkfun.com. This encoder has twelve detents per rotation, and each detent covers one complete

My kids are learning Morse code this summer, so I threw together this little circuit to help them learn. And to make it more fun… It uses an ATtiny85 ($2.26 at digikey.com) to drive a piezo beeper (≈ $3.50 at Radio Shack.) The ATtiny85 takes 5.5V max, so I built the circuit on a piece

Today, I made a small 3x3x3 LED cube with an ATtiny2313 that I had from about 2 weeks ago. Whenever I had to reprogram the LED cube when I thought of more awesome patterns, I had to get out my breadboard and then wire up everything again referring to pin-outs of ATtiny2313 and make sure

In this write-up, I’ll show how to create a value in Processing and then send this value over the serial port to the Arduino. In the example I’m setting values of LEDs making them brighter or dimmed but this example can be extended to control other items – which I plan to do later! Basically

If you want to RESET Arduino from the beginning without manually pressing the RESET button, there are a few ways. Here are two ways, using minimal wiring / circuitry. Step 1: Using 1 wire connected to the RESET pin 1. electronically, using only 1 wire connecting an OUTPUT pin (12 in this example) to the

Overview A software / hardware combo that allows for control of the analog filter inside a Commodore 64 that is running Cynthcart from a host computer (eg, Macbok, PC). Software • 16-step filter sequencer • Set the speed of the filter sequence (with intervals between values reaching 2ms) • Set the length of the sequence
