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 […]

AVR mini board with additional boards using attiny2313 microcontroller

Leave a Comment / AVR ATmega Projects, Development Board - Kits Projects /

Somewhat similar to PIC 12f675 mini protoboard, but extended and with additional boards. Using attiny2313. Step 1 Scheme Let us first start with a scheme. The scheme is pretty obvious since it only connects attiny2313 with the pins and the only additional elements are resistors and capacitor for reseting the microcontroller. Step 2 Bottom view

Swiss AVR Knife using Microcontroller ATtiny84

Leave a Comment / AVR ATmega Projects, Game - Entertainment Projects /

The Swiss AVR Knife bundles a number of AVR programming projects together in a single convenient Altoids Gum Tin. Because of the flexibility afforded by microcontroller programming, it also provides a starting point for any number of projects based on LEDs and sound output. The SAK can contain as many programs as the 8K of

You can’t calculate binary values “as is” on most handheld calculators and using the windows one is just a pain, so i decided to make my very own (binary only) calculator. This calculator supports all the basic functions like : NOT,OR,AND,XOR, addition,subtraction,multiplication,division and modulo. So join me as we are going to enter the world of ones and zeros

Stepper motor Driver Using AT2313 microcontroller

Leave a Comment / AVR ATmega Projects, Motor Projects /

Description With this circuit you can drive a unipolar stepper motor. It operates in full step mode. You can get a stepper motor from an old 5.25 disk drive. The AVR attiny2313 micro controller controls the pulses for the stepper motor. The pulses are amplified by the ULN2003 driver. The driver accepts 5V inputs, the
