0-99 Counter using AVR Microcontroller

In this tutorial we are going to design a 0-99 counter by interfacing two seven segment displays to ATMEGA32A Microcontroller. Here we count events based on number of times button is pressed. Before moving ahead, let's understand what is a seven segment display. A seven segment display got its name from the very fact that it has seven illuminating segments. Each of these segments has an LED (Light Emitting ...

Development system for PIC and AVR microcontrollers

After testing many systems development for PIC and AVR microcontrollers, none satisfy me. So I created this system with breadboard that has satisfied me. Step 1: More space free In this development system, I put two protoboards turned 180 degrees from each other. The space that is left to just enough space to insert a 40-pin microcontroller. But I'm planning to create a version with movables protoboards  to ...

Portal “Still Alive” on AVR microcontrollers

Yet another Portal-related instructable , but Different ! This one shows you how to :   1)Build a very cheap device that plays an 8-bit version of Still Alive from Portal 2)On the same hardware , but with a different chip , play the "radio tune" Here are both projects , in the same video (I hope the video quality does not affect how this entry is rated.I filmed it with a phone camera) :  Step 1: Parts List ...
