With this circuit you can drive a unipolar stepper motor. It operates in full step mode. 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 output for the driver is up to 30V so you can connect an […]

This small project let you make running leds. For this project you need a attiny2313 microcontroller and 8 leds and 8 resistors. The leds can be programmed so that they show differrent patterns. Hardware The leds are connected to PORTB of the microcontroller via the resistors that limit the current to 20mA. The project can
This is a Dot Matrix Scrolling Sign. A Dot Matrix Display has an 5×7 led matrix with 5 columns and 7 rows. The display is controlled by the ATMega328 microcontroller board. The rows are controlled by PORTB of the microcontroller, while PORTD puts the data on the columns to make the characters. The Dot matrix

This tutorial will give you a brief introduction to the concept of colors and how different colors can be produced using RGB LED. The color would be controlled using an ATMega16 microcontroller. RGB LEDs are basically the combination of the 3 LEDs (Red, Green and Blue) fused into a single package. It consists of four

Previously before 10-15 years the majority of electrical lights were either light bulbs (with yellow light) or tube-light sticks (with white light). The major disadvantage of these lighting devices was they consume more electrical energy (in terms of Watt) and gives less luminance (brightness). Light bulb wastes their most of the energy in form of
