About My kids have a plastic farm toy. It neighs, it baas, and frankly, it grates. But since I tricked it out with a microcontroller brain, at least it can play Simon. One of the marvels of parenthood is the sheer volume of noisy plastic junk that gets thrown your kids’ way. It makes tremendous hacking fodder. …
In this tutorial we are going to interface a 4×2 (8 key) touch keypad with ATMEGA32A microcontroller. We all know keypad is one of the most important input devices used in electronics engineering. This module does not have actual keys, but have specially designed capacitive metal pads, and these pads are very sensitive. So when a person …

To establish a good communication between human world and machine world, display units play an important role. And so they are an important part of embedded systems. Display units – big or small, work on the same basic principle. Besides complex display units like graphic displays and 3D dispays, one must know working with simple displays …
Introduction Our project consists of making a reflow soldering device using a normal toaster oven with a graphical LCD display for control and GUI. Soldering is an important and difficult task for custom printed circuit board design especially for integrated circuits that come as chip packages that are impossible to solder by hand. This is …

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 Z80 based project. Why the Z80? …
Introduction: One Sentence Sound Byte: “Grillzilla – A wireless meat grilling thermometer which alerts the user whether their entrée is cooked according to USDA recommendations via LCD and voice feedback.” Summary of what we did: As the weather starts to get warmer a common type of social gathering that occurs is the barbeque. Barbeques are all about …
Introduction The self adjusting window shade will automatically raise, lower, open, and close your blinds by itself. A computer terminal acts as a remote to broadcast instructions to the window shade via RF. These manual adjustments are stored into the microcontrollers system along with the rooms current ambient light and temperature settings. When these lighting …
Introduction Our project implements a smart algorithm in order to power a house with a photovoltaic, batteries or the power grid. For this project, we worked closely with a research team whose goal is to power a home with minimal power from the power grid. In order to form this smart home, we needed to …
About What is this thing? For our ECE4760 Spring 2012 (Microcontrollers) Final Project at Cornell University we decided to create a sous-vide cooker (a type of immersion cooker) that can maintain a set temperature for extended periods of time. It can auto-calculate the appropriate time for cooking a certain thickness of meat using heat transfer equations. …
This project is intended to perform the role of a goal-keeper in the popular arcade game Air Hockey. In this project, the robot shown below senses a puck coming toward it and moves in the direction of the puck’s motion so as to stop it. This problem was identified as fairly challenging to solve based …
