AVR Dual RGB Matrix Driver

Posted on: 29 Jun 2016

Multiplexing LEDs can be tricky, but we’re working with RGB LEDs, so think of each RGB as three individual LEDs. For an 8 x 8 matrix, that is 192 total LEDs on a single matrix. Even though there are only 32 connection pins, it is still possible to individually control the color and brightness of […]


AVR Chronograph from concept to PCB

Posted on: 28 Jun 2016

A chronograph is a device used to measure the speed of a passing object.  In it’s simplest form, this involves two sensors of some kind that ‘see’ the object, some device that can measure time, and some output to deliver the data to the user. In this instructable, I’ll be showing how I designed, programmed, […]

Posted on: 25 Jun 2016

This is a good project for beginners. It is easy to build.This running LED light uses seven bicolor led’s red and yellow, they light up in a pattern that can be made within the program code.The program code is written in assembler. ATMELs AVR STUDIO is used to write the program. The project uses the […]


LED thermometer

Posted on: 24 Jun 2016

his project shows the temperature on a three digit 7-segment display, it measures the temperature from -9.5 to 99 degrees Celcius in 0.5 C steps, or from 0 to 210 degrees Fahrenheit in 1.0 degrees steps. Because of the LED display the temperature is also readable in the dark. This project is available pre-assembled and […]


LCD interface

Posted on: 23 Jun 2016

This example is based on a LCD module with the Hitachi HD44780 LCD-controller.You can get these displays in various kinds, from 1 to 4 lines and from 8 to 40 characters per line. A display with 16 characters per line and 2 lines is used in this example. The display uses a power supply of 5V […]


RGB LED color mixer

Posted on: 22 Jun 2016

Page 1 of 4 An RGB LED is a LED which has three LED’s integrated in one packaging. These LED’s have the colors Red, Green, and Blue. The RGB LED used here is a hyperflux LED with common cathode, which can draw 20mA current. Such a LED costs about 2€. With these three colours you can […]


Stepper motor driver

Posted on: 21 Jun 2016

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 […]

Schematic and build Below is the schematic of the LED VU meter. The circuit is builds with the ATMega328 board an two LED boards connected to it. You can also build it on a breadboard. For more detail:  LED VU meter


Temperature indicator

Posted on: 19 Jun 2016

This project uses a Dallas DS1621 temperature sensor which indicates the temparature of the device. The temperature sensor has an thermal alarm output, which becomes high when the temperature of the device exceeds a user defined value. When the temperature drops below a user defined value, the alarm output becomes low. In this way any […]
