In this projects 8 different colors are displayed with the use of a RGB LED. The microcontroller that is used is the ATMega8. 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. Such a LED costs about 1 Euro. With these […]
Below is the schematic that shows how the IC is wired to the ATMEGA328 microcontroller and the 4 digit 7-segment display with comon cathode. Besides the MAX7219 you need only three other external components: two capacitors and one resistor. The capacitors are here to reduce noise signals and cannot be ommited. The resistor is used

This tutorial is meant for beginners in the field of Atmel AVR programming. I hope that you already read my first tutorial Blinking LED using Atmega32 and Atmel Studio. In most of the embedded electronic projects you may want to use a push button switch to give user inputs to the microcontroller. To use a

Story Introduction This is my first Arduino project. My work was inspired by several maker projects that created Persistence of Vision Displays [2,3,4]. Persistence of vision (POV) refers to the optical illusion whereby multiple discrete images blend into a single image in the human mind and believed to be the explanation for motion perception in cinema and animated films [1]. The

Story What is a Bootloader? Microcontrollers require a programmer to install firmware on them. A programmer is a device, that when combined with software, loads firmware to the microcontroller. There are many programmers available. I won’t go into to detail about them, but I will say that if you intend to do more than just

Story SSD1306xLED is a C library for working with the SSD1306 display driver to control dot matrix OLED/PLED 128×64 displays. It is intended to be used with the Tinusaur board but should also work with any other board based on ATtiny85 or similar microcontroller. The 128×64 OLED is controlled by a SSD1306 circuit and could be

I’m thinking about a new project, something a little unusual but still with a rich history of information upon which to base the build. On Tindie, I found the RC2014 project which is a build of a Z80 platform but based on some modern components. That got me thinking. My next project must be a

ATMega32 switch code is extremely simple to implement, and this article looks into how to write the code to make an LED light up when a switch is pressed. The atmega32-switch-code.c program tests the switch input to the ATMega32 Development System. There are many ways to write the code, but I have chosen the simplest
