About This project describes an open software open hardware pH meter using an Arduino/Freeduino board. In other words, this is an electronic circuit to be connected with a glass electrode pH sensor. It was possible by the idea from my friend Mr. Denis Vidal, the space that my supervisor gave me, prof. Dr. Emanuel Carrilho, BioMicS Group, Instituto de Química de São Carlos, Universidade de

As nice as an entertainment center with all the AV equipment neatly stacked behind a glass door looks, the ventilation leaves a lot to be desired, which meant temperatures inside the enclosure were often well in excess of 100F. I could just leave the door open while things were running, but that looked bad. At

I’ve always been interested in monitoring my local weather, and noticed the difference between what weather.com and accuweather.com think my local weather is, and what I see out the window. I also wanted better control over my heating and A/C system. As a computer and electronics nut, I’ve been playing with the Arduino Microcontroller, and decided

The open source project allows you to control DC appliances based on the temperature of two thermistor inputs. It uses AVR ATmega48 as main processor. The controller has both green and white LEDs to indicate status. The project output is connected to N-Channel MOSFET, AOD444, for switching with current up to 4A. For higher current you can use relay.
