RFID is the craze, found everywhere – from inventory systems to badge ID systems. If you’ve ever been to a department store and walked through those metal-detector-looking things at the entrace/exit points, then you’ve seen RFID. There are several places to find good information on setting up RFID, and this instructable focuses on installing the Parallax RFID reader (Serial TTL)

Got some scavenged stepper motors from printers/disk drives/etc lying around? Some probing with an ohmeter, followed by some simple driver code on your microprocessor and you’ll be stepping in style. Step 1 Get to Know Steppers Basically, you’re going to need to figure out where all the little wires go. First step is to figure

When I was first working with AVR microcontrollers, I relied a lot on tutorials I found on the web, but nearly all of them raised the question of how to attach a programmer to the microcontroller when you aren’t using a development board. Most of the time, I would see people shoving pieces of wire into the

If you cannot afford to buy a USB programmer for AVR, don’t worry, you can make one by yourself. This programmer uses a Atmega8 microcontroller with a few external passive components. The good thing is you don’t need any USB controller because it is implemented in the firmware inside Atmega8. Yes, you are right, you
