“The console is designed as platform for learning digital electronics and C#: we’re in the process of writing a book covering all aspects of building the console, how its components work and how to write games for it with our framework.”

“Cade9 is my small embedded project consisting of ATmega32 MCU with custom hardware which I hand soldered on a matrix board. This was my undergraduate 3rd year minor project. It uses the open source cocoOS as scheduler. On top of CADE9 one can implement classic arcade games like snakes, pong, bricks, breakout etc.”

“Awhile back I was working on a project that that I wanted to be able to start music the on my mac through the IR receiver. After a while of looking around I found this library which allows you to use your arduino as an Apple Remote. I integrated it in to my project and it worked great! So the other day I decided to make an Apple Remote shield for my arduino.”

“Each time the PCB passed at 12h00 a hall effect sensor sensed the magnet and generated an interruption. At this time, we have to check the counter to see how many ticks had been passed from this rotation since the last rotation, took this value and divided it by 360. This calculation then gives you the time between each degree.”

“A Digital Voltmeter (DVM) is one of the first things you need if you’re building electronics projects. Most of us have one. But what if you need more than one? Enter the Arduino. If you have an Arduino that can drive an LCD, you’ve got a multi-channel voltmeter!”

“The protocol is very simple between OpenCV and Arduino: the program transmits one integer per line through the serial connection (using the USB connection or a RS232 port). Each integers gives the position (in microseconds) to where the servo should move.”

“Using an ATmega 2560 and therefore the heart of Arduino, we have developed a remote control with GSM. This allows to control 2IN/2OUT, DTMF key, gate control and GSM thermostat activated remotely. The control is simple to use, thanks to the availability of several libraries that allow you to do anything to the Arduino; if there is not really a specific library, you can modify an existing one.”

“This project is based on obdev’s RemoteSensor and their firmware only USB implementation, the main change is the replacement of the analog sensors with a SHT11 digital temperature and humidity sensor. The sensor unit consists of an ATTiny45 MCU, a SHT11 sensor, and a hoperf RFM12 868 MHz transceiver module. It is powered by 2 AA cells and is expected to give >1 year of battery life.”

“This project shows how to use a simple thermistor to measure temperature and display the temperature graphically on a Nokia 3310 LCD. Thermistors are incredibly cheap (about 50 cents), and provide fractions of a degree accuracy.”

“Do you often forget to irrigate your plants? Do you have to ask your neighbors to take care of them when your whole family is out for a vacation? Don’t worry any more! Here is a solution. This embedded system, worry-free automatic timed plant feeder, can do all these services for you…It can: regularly feed water to your plants for a specified amount of water; and also be used as an alarm clock.”
